Description

Description: TECHNICAL FIELD The present invention relates to a coffee bean cleaning plant.

(Prior art) Conventionally, coffee beans have been packaged and harvested from the producing country and imported. Imported coffee beans, which were heavily contaminated, were conventionally roasted.

(Problems to be Solved by the Invention) Conventionally, imported coffee beans, which were considerably contaminated, were roasted as they were, but the quality was deteriorated and the taste was impaired. However, coffee beans are quite hard and can be washed with water or dried by heating.

Further, after washing with water and polishing in a heated state, a beautiful luster is obtained, which is extremely advantageous for trading of coffee beans before roasting.

(Object of the Invention) An object of the present invention is to obtain a plant for washing, drying and polishing coffee beans before roasting.

(Means for Solving the Problems) In the present invention, an original coffee bean supply port 3 is provided at an upper portion of a vertical cylinder 2 having a spiral blade therein, and a discharge port 4 is provided at an arbitrary position in the upper and lower portions. A flushing section 1 provided with a drain 6 at a desired position and a hot air supply port 7 at a desired position, and a supply port 10 formed at an upper portion provided in the vicinity of the flushing section 1 and a discharge port 11 formed on a side face, and a lateral feed spiral is formed inside. A stirring and drying device 8 provided with a stirrer, a hot air generating device 9 which divides hot air into two, one of which is connected to the hot air supply port 7 of the washing section 1 and the other of which is connected to the hot air supply port of the stirring and drying device 8; An elevator 12 extending from the outlet 4 of the washing section 1 to the supply port 10 of the stirring and drying device 8;
The first polishing machine which formed 15 and provided with a traverse spiral polishing body inside
13, a lift 16 from an outlet 15 of the stirring and drying device 8 to a supply port 14 of the first polishing machine 13, and a supply port 18 opened at an upper portion provided at a lower portion of the first polishing machine 13 and Outlet 19

Further, the hot air supply port 7 is opened at a position higher than the water injection port 5. That is, when the raw coffee beans are supplied from the supply port 3, the dirty skin rises while being washed with water, heavy stones and the like flow out of the drain 6, and the washed coffee beans are discharged from the discharge port 4.

A stirring and drying device 8 is provided near the washing unit 1, and a hot air generator 9 is provided below the stirring and drying device 8. A supply port 10 is formed at the top of the stirring and drying device 8, and a discharge port is provided at the front side.
11 is formed, and a helical agitator is fed inside.

The hot air generator 9 splits the hot air into two,
And the other is connected to the stirring and drying device 8. Washing part 1
Between the agitating and drying device 8 and the agitating and drying device 8, there is provided an elevator 12 from the outlet 4 of the washing section 1 to the supply port 10 of the agitating and drying device 8.

A first polishing machine 13 is provided near the stirring and drying device 8.
A horizontal feed spiral stirrer is provided in the first polishing machine 13, and a supply port 14 is formed at an upper portion and a discharge port 15 is formed at a side front surface.

An elevator 16 is provided between the stirring and drying device 8 and the first polishing machine 13 so as to extend from the outlet 11 of the stirring and drying device 8 to the supply port 14 of the first polishing machine 13.

A second polishing machine 17 is provided below the first polishing machine 13. A supply port 18 is opened at the upper part of the second polishing machine 17, and a discharge port 19 is provided at a side portion. The discharge port 15 of the first polishing machine 13 is connected to the supply port 18 of the second polishing machine 17.

A stone remover 20 is provided near the second grinder 17. 21 is a supply outlet, 22 is a grain outlet, and 23 is a stone outlet.

(Operation) Next, the operation will be described.

The hot air generator 9 is started to supply a part of the hot air to the hot air supply port 7 and the rest of the hot air to the stirring and drying device 8. Water is injected from the water inlet 5 and drained from the drain 6.

When raw coffee beans are supplied to the supply port 3 in this state, the soiled coffee beans rise while being washed with water, and those that have been washed are discharged from the discharge port 4.

In this case, the coffee beans rise while being spirally agitated, so that the beans are washed uniformly. Further, since the hot air from the hot air generator 9 is supplied to the hot air supply port 7, the coffee beans during the washing are steamed with steam. Removed, has a great water-washing effect.

The washed coffee beans go up the elevator 12 and flow into the supply port 10 of the stirring and drying device 8. The stirring and drying device 8 has a discharge port 11 formed on the front side, and a horizontal feed spiral stirring body is provided inside. The drying hot air from the hot air generator 9 is supplied. It is drained while being laterally fed by the feed spiral stirrer, and is almost dried by hot dry air. The coffee beans discharged from the outlet 11 of the stirring and drying device 8
The drying is quick because of the high temperature.

The raw coffee beans flowing out from the outlet 11 of the stirring and drying device 8 cannot completely remove moisture by this process alone.
And is supplied to the supply port 14 of the first polishing machine 13. Therefore, when the first polishing machine 13 agitates and polishes under high pressure, gloss is generated. Since the polishing is repeated by the second polishing machine 17, the cooling is also performed during this time.

(Effect) Conventionally, coffee beans have been imported from their producing countries in bags as they were harvested. Imported coffee beans were considerably contaminated, but they were roasted in the past,
Poor quality and poor taste, and the coating of the operator was dirty.
