Description

Coffee hull peeling and silver peeling machine

The invention relates to a husking device for green coffee beans, in particular to a husking and silver peeling machine for green coffee beans.

The coffee fruit is bright red and is also called "coffee cherry" because it looks like a cherry. The coffee fruits are from outside to inside, respectively: (1) exocarp, (2) pulp, (3) pectin, (4) endocarp, (5) SilverSkin / Chaff, and (6) coffee seeds ( Coffee beans); After the coffee fruits are harvested, they need to go through many complicated processing steps before they can take out the core coffee seeds (coffee beans), and then use subsequent roasting to become coffee brewing coffee. Roasted coffee beans for drinks.

After the coffee fruit is removed from the tree, the outer peel, pulp and pectin must first be removed. This process is called raw bean processing; common raw bean processing methods include: sun exposure, water washing and semi-water washing. No matter which method is used, the coffee fruit must be dried through the raw bean treatment step to reduce the moisture content to 10% to 14% (the product obtained after the raw bean treatment step is referred to as coffee raw bean hereinafter) Then, using a dehulling machine to remove the inner peel and silver skin of the raw coffee beans is the coffee bean. After roasting and grinding the coffee beans, they can brew a strong coffee beverage.

In the approved and published Chinese Real Month New Patent Authorization Bulletin No. CN203969153U, a coffee dehulling, polishing and grading all-in-one machine is disclosed. A feeding port is arranged above the bin, a polishing bin and a bracket are provided at the bottom of the shelling bin, and the polishing bin is fixedly connected to the bottom of the shelling bin; a plurality of shelling rollers are arranged inside the shelling bin, and a number of shelling rolls are connected by a connecting rod, and a number of shelling The rolls are arranged in a “V” shape from top to bottom.

The positional relationships described in the following embodiments include: up, down, left, and right. Unless otherwise specified, they are based on the directions of components shown in the drawings.

Preferably, the dehulling and descaling machine for coffee green beans of the present invention is suitable for including but not limited to: coffee green beans and other dried shelled fruits or cereals with a shell. In order to be distinguished from coffee fruits, the "coffee green beans" referred to in the description of the present invention refers to the product of coffee fruits after passing through the green bean processing step. In other words, the "coffee green beans" referred to herein refers to the Those who did not remove the endocarp shell and / or silver skin after bean treatment.

First, please refer to FIG. 1 to FIG. 5, which are structural exploded views, structural appearance views, structural side views, and structural cross-sectional views of an embodiment of an unhulling and silver peeling machine for coffee green beans according to the present invention.

When the dehulling and descaling machine for green coffee beans of the present invention is not started, the gap between the wheel surface of the first rolling rod 11 and the wheel surface of the second rolling rod 12 is called a "normal gap". The technical concept of the coffee green bean hulling and silver peeling machine according to the present invention, this normal gap can be adjusted and changed by a gap adjusting mechanism. The advantage of this design is that an appropriate normal state can be adjusted in advance according to the size of the green coffee beans. gap. Because the gap of the traditional technology is fixed, if the size of the raw coffee beans is smaller than the size of the fixed gap, the raw coffee beans will easily pass and cannot be squeezed and shelled and / or peeled, otherwise If the particle size of the green coffee beans is larger than the size of the fixed gap, it will be easily crushed to increase the crushing rate of the green coffee beans.

When the green coffee beans pass through the gap between the wheel surface of the first rolling rod 11 and the wheel surface of the second rolling rod 12, if the particle size of the green coffee beans is larger than the size of the normal gap, the green coffee beans will pass the second The rolling lever 12 is pushed away from the first rolling lever 11, in other words, the movable member 20 and the second rolling lever 12 can be freely moved to the dynamic direction P2 in the first direction to increase the gap (see Fig. 7-2). At the same time, the adjustment mechanism will provide a spring force to apply a pushing force to the movable part 20, so that there is still a proper pressing force between the first rolling rod 11 and the second rolling rod 12 to break the outer shell of the coffee beans and / or The silver skin separates the shell and / or the silver skin from the coffee beans. After the green coffee beans with a larger particle size pass through the gap, the elastic force of the spring 30 will turn the movable part 20 and the second rolling rod 12 toward the first. Pushing in the direction of the rolling lever 11 is used to push the movable part 20 and the second rolling lever 12 from the dynamic position P2 back to the normal position P1 until the movable part 20 is blocked by the first slider 22, at which time the first rolling The gap between the pressure lever 11 and the second rolling lever 12 will return to the normal gap that was initially adjusted. .
