Description
Technical field
The present invention relates to a kind of technical field of refrigeration equipment, more particularly to a kind of family expenses ex situ freeze dryer.
Background technology
With the improvement of living standards and healthy diet pay attention to day by day, the storage request to family's fresh food is more next
It is higher.The conventional fresh food storing mode of current family includes Cord blood, High temperature storage, dehydrated preservation and pickled.It is low
Temperature preserve in using it is most common be refrigerator preserve.Low temperature can reduce or stop the reproduction speed of microorganism in food, slow down
All chemical reaction velocities in food.It but Cord blood can not kill microorganism, can only drop effect of the microorganism to food
Low, simultaneously because the effect of various enzymes, at low temperature, food, which is not avoided that still, becomes sour rotten.
Freeze-drying has a clear superiority compared with above-mentioned food storage method.Freeze-drying is first by food freezing
The moisture in frozen food is distilled under high-vacuum environment again afterwards, therefore dried food keeps original chemistry
Composition and physical property, by cryofixation, are not acted on, the volume of food is hardly by surface tension in the drying process
Become, it is loose more empty, in spongy, original structure is maintained, almost recovers original character after adding water immediately.Moreover, distillation
Avoid in general drying means because the inorganic salts entrained by the moisture to surface migration of food therein surface separate out and caused by
Case-hardened phenomenon.
Family expenses freeze dryer at present on the market is less, and is freeze dryer in situ, and freeze dryer in situ carries pre-freeze function,
Food can be completed in cryodesiccation chamber by being chilled to lyophilized overall process, and food need not be shifted.But freeze dryer in situ only has one
Individual cryodesiccation chamber, the food after freezing can not be freezed several times.

Beneficial effects of the present invention are as follows：
1st, refrigerating chamber and cryodesiccation chamber are provided with casing of the present invention, the food of freezing can be first stored in refrigerating chamber, it is necessary to when edible
Measure and freezed from the part or all of food of refrigerating chamber taking-up according to demand, lyophilized leftover can not continue to be placed on freezing
It is indoor.This structure can meet the requirement that food can be freezed at any time on demand, save the time that refrigerating process is consumed, refrigerating chamber
Other foods for needing to freeze can be deposited, lyophilized operation is not influenceed, serves the effect for saving the energy, improve freeze dryer
Utilization rate.
2nd, freeze cycle loop of the invention and lyophilized circulation loop use a compressor and a condenser, therefore energy
Reduce manufacturing cost and operating cost, moreover it is possible to save the energy.
3rd, condensed in freeze cycle loop of the invention between condensator outlet and freezing expansion valve, in lyophilized circulation loop
Device, which is exported and freezed, is equipped with magnetic valve between expansion valve, therefore can independently be precisely controlled freeze cycle loop and lyophilized be recycled back to
The cryogenic temperature on road.
4th, filter is equipped with freeze cycle loop of the invention and lyophilized circulation loop, filter plays removal refrigeration
The effect of impurity and moisture in agent, it is ensured that equipment is normally run, moreover it is possible to increase the service life of equipment.
5th, refrigerating evaporator of the invention is provided with the freezing electric heater of defrosting, freezes evaporator provided with the lyophilized of defrosting
Electric heater, electric heater can be defrosted to evaporator in time, and the thermal resistance of room air between reducing evaporator and being each can be improved

Degree.Filter can play a part of impurity screening and moisture.
The general principle of freeze-drying is the tri-state change based on water.Water has solid-state, liquid and gaseous state, and three kinds of states both may be used
It can be coexisted again with mutually changing.When water is in three phase point（Temperature is 0.01 DEG C, and water vapor pressure is 610.5Pa）When, water, ice, water
Steam three can coexist and mutually balance.Under high vacuum state, using sublimation principle, make the water in the material that freezes in advance
Point, without the thawing of ice, directly it is removed with the distillation of ice state for water vapour, so as to reach the purpose of freeze-drying.Lyophilized system
Product in it is spongy, without drying shrinkage, rehydration be fabulous, moisture content is few, can long-time storage and transport at normal temperatures after corresponding package.
This is using the new course of work：
When refrigerating chamber 12 works, compressor 1 starts.Refrigerant by compressor 1 compress after enter condenser 4 condense after by
Evaporated after freezing and filtering device 10, freezing magnetic valve 9 and freezing expansion valve 8 into refrigerating evaporator 2, freezing and evaporating in evaporation process
Heat in the absorption refrigerating 12 of device 2 realizes that refrigerating chamber 12 freezes, and the cold-producing medium stream after heat exchange returns compressor 1.
When cryodesiccation chamber works, compressor 1 starts.Refrigerant enters after condenser 4 is condensed after being compressed by compressor 1 to pass through
Evaporated after crossing lyophilized filter 7, lyophilized magnetic valve 6 and lyophilized expansion valve 5 into lyophilized evaporator 3, freeze and steam in evaporation process
The heat that hair device 3 is absorbed in cryodesiccation chamber 14 realizes that cryodesiccation chamber 14 freezes, and the cold-producing medium stream after heat exchange returns compressor 1.It is lyophilized
Vavuum pump 11 is opened needed for the temperature of room 14 reaches during temperature, at this moment cryodesiccation chamber 14 is in low-temperature negative-pressure state.
Need first to open freeze cycle loop during freeze dried food, food is put into refrigerating chamber 12, be then turned on cryodesiccation chamber 14
Lyophilized circulation loop, the food that freezing is completed after vavuum pump 11 is opened when temperature needed for the temperature of cryodesiccation chamber 14 reaches and is put into
In cryodesiccation chamber 14, and freezing magnetic valve 9 is closed.Magnetic valve 9 is freezed when also having food in refrigerating chamber 12 to keep it turned on.
According to the observation to food freeze-drying process, the time that direct current electric heating plate 13 is opened is judged.Confirm lyophilized operated by observing
