Description:
Description PEELING MACHINE OF DRY COFFEE SEED COLLIDING SYSTEM Technical Invention Area This invention related to the peeling machine of dry coffee seed colliding system, this innovation related to colliding force or dry coffee seed colliding force that consist of impact force and axis centrifugal force.

The background of the invention Peeling tool of dry coffee seed that is commonly used now is a traditional system, which consists of series tools made from wood attached with pestle on the tip. The tool is activated with foot by pedaling or pestle that is pounded with hand.

The second tool is peeling wet coffee seed in semi manual form. This tool has a pressing wet husk system with tread of screw activated by cranking it using hand.

Invention Summary The invention of peeling machine of dry coffee seed colliding system consist of main part called rotor axis. This rotor axis attached three metal sheets circle. Each of them has 7 mm thick and takes circle shape. Then, at the edge of metal sheets circle attached colliding axises flatly. The function of colliding axis is to collide coffee seed to the rammed partitions with capacity of colliding is 2 or 3 kg/minute.

Rammed partition functioned to receive or restrain impact force centrifugal rotor axis force, and located as well as possible in order the position close to the colliding axises. The purpose of this position is to rub the coffee husk that has already collided, so that the coffee husk would be easy to strip and to clean a whole their husk. Colliding partition consist of colliding box. The box form is a cylinder shaping attached metal with flat corner inside by using electric arc welding. This colliding partition is also completed by funnel on the tip and exit door on the under cylinder, also two closed wall at the two end cylinder.

The Detail Description of the Invention The power and the torque resulted by first mover such as gasoline fuel engine, diesel fuel engine, turbine etc. can be directed through Transmission Belt, Chain, Gear Wheel, Clutch and others, in order to use subsequently those power and torque, such as to drive the load and provide the forces needed.

The power and torque transmitted by those Belt, Chain, Clutch and Gear Wheel usually will be distributed through their pairs respectively, they are chassis part, fixed clutch, gear wheel with identical type ones.

The next role in transmitting the power and the torque conducted which those chassis part, clutch, sprocket, and gear wheel are mounted.

The power and the torque that have existed on the main axle can be mostly mediate used, and also transmitted anymore to the next axle, that is level one, two, three, four and so forth in order to drive the load.

In addition to drive and swing the load, the powered axle and the torque also provide the centrifugal force to the peripheral. By installing the plates rounded with the certain diameter, the centrifugal forces exist on that axle can be increased and easier to use.

Installation of the plain small axle on external diameter side of the installed plate upon that axle, this centrifugal force on axle can be the grains force of crushing as the coffee, etc.

The grains crushed by this centrifugal force needed to collide and scrub, so that dried coffee grain skins can be removed; it is necessary to make the crusher wall as such a shape that can be also mentioned as the Crushing House. The construction should be designed as such a shape, so that it enables to withstand the present forces and can use those forces maximally.

The chief part of the drying coffee grain remover machine with this crushing system is an axle. The axle used according to the loading is the transmission axle. This axle type gets the pure twist or twist and flexible. Therefore, in the maintenance and the determination of the axle need to regard the strength, clumsiness, substance, and axle diameter.

Because the placement between the train axle of engine and the axle driven (crushing rotor axle) are rather far away, the transmission type used upon this machine is the belt transmission and V belt type selected.

The V belt is made of rubber and have the receptacle as the core belt in order to bring the larger towing. The V belt also twisted at surrounding V shaped chassis part line. There are two types of chassis part: the smaller train chassis part and the driven chassis part/the chassis part upon the axle rotor in larger diameter which also act to lower the swing from the train motor.

The two axle tips placed upon the machine frame by installing on two ball bearings in Beam position.

The source of power and torque as the first mover of this machine is gasoline fuel motor. Subsequently, the motor power and the torque of this driving source transmitted through the V belt to the chassis part moved for further of the power and the swing to be continued to the main axle/or to the rotor axle, and then it will move/or swing concurrently with the crusher axles, after approximating the stabilized rotor swing at more or less two

minutes from initial start (as well as the machine warming), then the drying doffée gwamsfflsFt put into the entry funnel continuously or as desired.

The coffee grains enter through that funnel immediately accepted by N&e"o-tor., an& persistently brought by the crusher axle at high speed in order to collide into the crushing wall at high impact and centrifugal forces continuously, so that coffee grains are crowded at high pressure within the triangle corner room on the crushing teeth inside, as well as any slot between the crushing teeth end with the crusher axle.

As a result of the crushing and the scrubbing at high force and speed, then the drying coffee grain skin will be removed from its grain. Subsequently, the removed coffee grains and the crushing skin will fall down through the slot between the crushing teeth and the crushing axle towards the grain sieve at exit door beneath the crushing house in order to run into the available accommodating place.

The unclean coffee grain from its skin may not pass through outside sieve and will be directly brought back upper by the crusher axle for doing the re-crushing until it cleaned at all.

The invention of this drying coffee grain remover machine with the crushing system has several benefit or advantage as follow: 1. This machine has the chief part that is rotor axle, in which upon the chief axle it is installed three plates at seven mm in thick with its piece in circle shape of more or less 25 cm in diameter. And the, on the plate edge of circle installed the crusher axles evenly.

This crushing axles act to collide the coffee grain to the crushing wall with the capacity of more or less 2-3 kg/miriutes.

2. The next very typical and important part of this machine is equipped with the crushing wall that act to accept/or withstand the impact and rotor axle centrifugal forces, as well as to be positioned as such a shape, so that its location closed to the crusher axles in order to able of scrubbing the crushed coffee skin, so that it is easy to remove and clean at all.

This crushing wall occurred from the crushing house which is cylindrical shape and to be installed with the corner iron inside evenly by using the electrical arch weld. This crushing wall is also equipped with the access door and the funnel on upper and the exit door or the grain sieve on the bottom of the cylinder as well as two closed walls on the tips.
