Description

An intensive production system for treating food waste by using black soldier flies

technical field

The utility model belongs to the technical field of kitchen waste treatment, and relates to an intensive production system for processing kitchen waste by utilizing black soldier fly breeding.

Background technique

With the rapid economic development and the process of urbanization, the amount of kitchen waste is increasing year by year, and the consequent pollution problem is also becoming more and more serious. Kitchen waste is rich in a large amount of organic matter, and the recycling of solid organic matter has become an important factor in the profitability of the project. In the traditional process, the solid organic matter is ground into slurry and injected into the anaerobic tank for digestion and biogas production. Due to the complex composition of garbage, problems such as mechanical wear, pipe blockage and even anaerobic acidification will occur in grinding, pumping, dehydration and other links. In addition, the generated biogas needs to be purified and reused, and the problem of the exit of the generated biogas residue has also become a major difficulty. Therefore, the resource utilization of solid organic matter needs to find another way. Insect breeding represented by breeding black soldier flies has become a better alternative. The life cycle of black soldier flies is 40 to 45 days. It goes through five stages: egg, larva, pre-pupa, pupa and adult. After breaking the pupa and adult, it mates and lays eggs, and then it will die after about a few days of survival. About 10 days after hatching from eggs into larvae, black soldier fly larvae live in saprophytic life, feeding on decomposed organic matter such as kitchen waste, animal feces, animal and plant carcasses, and can efficiently convert food into their own nutrients. An important link in nature's detritus food chain.

The characteristics and economic value of black soldier flies make it a perfect solution to cultivate black soldier flies using organic matter from kitchen waste. The treatment of organic solid waste with black soldier flies can feed food waste (about 80% moisture content) to black soldier fly larvae, and finally obtain 80% of high-quality insect protein and 20% of nutrient-rich insect manure organic fertilizer . The raised worms can be used as protein source feed for aquaculture, and the worm manure can be directly returned to the field as organic fertilizer. In this way, the use of organic solid waste to raise insects not only disposes a large amount of waste and turns waste into treasure, but also provides a large number of cheap production raw materials for our insect breeding system, reducing production costs, and the entire treatment process is harmless and resourceful. .

At present, there are two ways of breeding black soldier flies. One is mainly artificial breeding. The workers work between simple breeding racks, which is inefficient and cannot be promoted on a large scale. The other is the automated system breeding method. The existing system equipment has complex structure, cumbersome process, large floor space, high cost, and inconvenient maintenance and maintenance. Especially in the process of fabricating and turning boxes, more intensive, simple and efficient automation equipment and systems are required. In addition, existing aquaculture plants generally face the problems of environmental temperature regulation and deodorization. The environmental temperature has a significant impact on the growth and development, spawning and hatching of the black soldier flies, and the most suitable temperature is about 25-30 degrees. When the temperature drops below 15 degrees, it grows slowly or hibernates, and when the temperature falls below 5 degrees or exceeds 35 degrees, it is easy to die. In terms of deodorization, the odor in the breeding workshop is rich in ammonia and hydrogen sulfide, mainly from the decay of food waste materials and the metabolism of black soldier flies. The odor is directly discharged without treatment, which is easy to pollute the environment; but if the odor of the entire breeding factory is collected and processed, the energy consumption of the exhaust fan will be huge, and the cost of deodorization will be high.

The specific operation process is as follows:

(1) Pretreatment and conditioning of culture medium

The solid organic base material of kitchen waste after pretreatment such as screening and degreasing, with a moisture content of about 80% and a particle size of less than 50 mm, is transported to the kitchen waste preparation room 1.

The transport vehicle pours the kitchen waste into the mixing tank 2, adds auxiliary materials, and mixes and stirs the two to form a culture material. The material at this time is a thick substance, which has a certain fluidity, is easy to transport, and is easy for the black soldier fly larvae to eat and grow. The homogenized culture material flows to the temporary storage bin 5-1 on the suspension feeder 5 via the conveying steel pipe 2-2. After the temporary storage bin 5-1 is filled with the culture material, the feeding is stopped.

(2) Cloth and feeding

A group of multiple feeding pipes 5-3 are arranged at the bottom of the temporary storage bin 5-1 of the suspended distribution truck 5, which are arranged in a single row and multi-layered, and are individually controlled by a plurality of feeding control valves 5-2. In the cloth working state, only one of the feeding control valves 5-2 is opened, and the culture material is transported into the culture box 7 of its corresponding layer. Each breeding box 7 was pre-inoculated with 4-day-old black soldier fly larvae.

When the feeding of a certain breeding box 7 is completed, the suspension feeder 5 is started to move horizontally along the track 8 of the suspension feeder to feed the next adjacent breeding box 7 on the same layer. With the horizontal movement of the suspended feeder 5, the fabric of the single-layer culture box 7 is completed.

From top to bottom, when a single layer of culture box 7 is finished, the corresponding feeding control valve 5-2 is closed, and then the feeding control valve 5-2 corresponding to the next layer of culture box 7 is opened, Move the cloth to the subsequent next layer. Such a reciprocating cycle until all the breeding boxes 7 on all the breeding racks 6 are completely filled with the culturing material.

The suspended feeder 5 is arranged on the ceiling of the breeding room 4, and the material flows from top to bottom, which simplifies the tedious distribution process and improves the automation level. The feeding control valve 5-2 set on the suspension feeding truck 5 can control the material flow and realize quantitative feeding of black soldier fly larvae; After the materials are put into the breeding box 7, the black soldier fly larvae begin to feed day and night and grow day by day. In order to improve the conversion rate of kitchen waste and reduce the residue of kitchen waste, the frequency of punching is fixed at twice a day.

(3) Turning box collection and screening and packaging

Black soldier fly larvae are cultivated to the harvest season, that is, when the eggs are cultivated for 15 to 17 days, the breeding box 7 is mainly composed of grown adults, black granular insect excrement, and a small amount of residual food waste culture material. The next step is to collect and collect black soldier fly adults and feces. In the stage of turning the box and collecting, start the cylinder actuator 6-6 on the breeding rack 6, and drive the bracket 6-5 to turn up slowly until the angle between the bracket 6-5 and the upright support frame 6-2 is less than 45 degrees.

After the breeding box 7 is emptied, the cylinder actuator 6-6 is activated to reset the bracket 6-5 and the breeding box 7 until it is level.

In the separation operation device, the mixture of adult black soldier flies, insect excrement and a small amount of food waste culture material is vibrated on the vibrating screen machine 11, and the insect excrement particles are relatively fine, which can pass through the lower sieve hole of the vibrating screen machine 11 and fall into the The conveying belt of the second climbing belt conveyor 16 is conveyed to the insect manure temporary storage box 17; the adult black soldier flies and fresh insects fall to the conveying of the horizontal belt conveyor 14 through the upper discharge port of the vibrating screen 11. On the belt, it is conveyed to the dryer 12. After drying at 45~55℃, the fresh worms of black soldier flies turn into dried worms. The dry worms are transported to the dry worm temporary storage box 18 via the first climbing belt conveyor 15 . The worm feces and dry worms entering the temporary storage box are respectively measured and packaged by their respective metering balers 13 .

(4) Deodorization

The entire breeding room 4 is sealed, and the odor is introduced into the odor washing tower 20 by the negative pressure suction of the external odor induced draft fan 19 . The odor entering from the bottom of the odor scrubbing tower 20 flows upward along the tower body. The odor containing pollutants such as ammonia gas is firstly washed in direct contact with the circulating liquid in the liquid storage chamber 20-6. The odor after preliminary washing continues to rise in the tower body, passes through the packing layer 20-4, and cooperates with the water mist sprayed by the first sprayer 20-3 to carry out secondary chemical washing of the odor gas. When the odor containing pollutants passes through the packing layer 20-4, the pollutant molecules (mainly ammonia) in the odor will be intercepted and blocked by the liquid film on the filler, and the pollutant molecules will be transferred from the gas phase to the liquid phase. phase, and chemically react with hydrochloric acid in the liquid phase, so as to be adsorbed and neutralized to achieve the purpose of deodorization. Finally, the deodorized gas is demisted by the mist eliminator 20-2 and then discharged from the exhaust pipe 20-1.

The pH meter 23 is used to detect the pH of the circulating liquid, and when the pH of the circulating liquid is equal to 7, the acid liquid replenishing pump 22 is turned on, and the hydrochloric acid solution in the hydrochloric acid storage tank 24 is supplemented to the water in the tower through the second sprayer 20-5. Liquid storage chamber 20-6. The hydrochloric acid solution in the liquid storage chamber 20-6 is lifted to the first sprayer 20-3 through the circulating pump 21 and the circulating pipeline 25, and the sprayed liquid contacts the odor, absorbs the alkaline gas components in the odor, and returns to the first sprayer 20-3. to reservoir chamber 20-6. When the liquid in the liquid storage chamber 20-6 needs to be drained out, the drain port 20-7 is opened.

The aquaculture production system can be completed automatically, such as material transportation, feeding, collection, screening, drying, metering and packaging, deodorization and other links, without the need for personnel to operate, with high work efficiency, and the output of dried black soldier flies and Insect manure can be used as a resource and has economic benefits.
