Description

Coffee bean conveying trough

Technical Field

The utility model belongs to the technical field of the coffee beans is carried, a coffee beans conveyer trough is related to.

Background

Coffee beans are plant fruits used to make coffee. Before the coffee is made, the coffee beans are required to be baked (5-25 min), the directly picked fruits, namely raw beans, are processed into cooked beans which are rich in fragrance and can skillfully express fragrance, sour taste and bitter components, and the coffee can be obtained by brewing the cooked beans after the cooked beans are crushed.

In the deep processing process of coffee beans, the coffee beans are often conveyed among various devices, in the prior art, generally, a conveying belt or a vacuum pump is adopted to be matched with a pipeline for conveying, the conveying process of the conveying device is driven by electric power, the operation cost is high, the structure of the conveying device is complex, meanwhile, in order to ensure the uniformity of the quality of the coffee beans, the coffee beans are often required to be screened for multiple times in the processing process of the coffee beans so as to select the coffee beans with the approximate size, and the cost of a special screening device is high.

Therefore, the development of the coffee bean conveying trough which has low operation cost, simple structure and screening function is of great practical significance.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the comparatively complicated and higher defect of running cost of prior art structure, provide a running cost is cheap, simple structure and have the coffee bean conveyer trough of screening function.

In order to achieve the above object, the utility model provides a following technical scheme:

a coffee bean conveying trough comprises a trough I, a trough II and a trough III which are sequentially connected from top to bottom; the middle section of the groove II is provided with a filter screen, the included angle between the central axes of the groove I and the groove III and the horizontal plane is 25-35 degrees, and the included angle between the central axis of the groove II and the horizontal plane is 55-65 degrees.

The coffee bean conveying groove of the utility model has simple structure, can realize the conveying of coffee beans through the action of gravity, skillfully adopts the design of three sections of chutes, wherein, the slope of the middle chute is larger, when coffee beans are poured on the groove I positioned at the upper end, the coffee beans slide downwards along the groove I under the action of gravity, the slope of the groove I is smaller, the sliding acceleration is smaller, the excessive coffee beans can be prevented from reaching the groove II, the filtering effect of the filtering net on the coffee beans is further influenced, the slope of the groove II is larger, the coffee beans can accelerate in the groove II to reach a faster speed, on one hand, the conveying speed of the conveying groove can be accelerated, on the other hand, the speed of the conveying groove is faster, the coffee beans passing through the filtering net can be prevented from blocking the filtering net to a certain degree, meanwhile, the coffee beans can receive the resistance of the filtering net when passing through the filtering net, the speed of the conveying groove is slowed down, and finally, the conveying process is completed. The utility model discloses a slope of groove I, groove II and groove III is specific, and it is through specific and the slope of mutually supporting groove I, groove II and groove III can carry out effectual filtration to coffee beans when having guaranteed conveying speed. The gradient of the groove I is too slow, the coffee beans are difficult to reach the required speed, on one hand, the conveying speed is too slow, on the other hand, the coffee beans are easy to form accumulation at the filter screen, and the continuous conveying is difficult to realize; the slope of the groove I is too large, the coffee beans in the groove II are too much, and the coffee beans are accumulated at the filter screen; the gradient of the groove III is too slow, and the conveying speed is too slow; the slope of the groove III is too large, so that the speed of the coffee beans reaching the tail end of the groove III is too high, and the coffee beans are easily damaged; the gradient of the groove II is too slow, the acceleration effect of the coffee beans in the groove II is not obvious, and the effective filtration of the coffee beans is difficult to ensure; the slope of the groove II is too large, and the speed of the coffee beans reaching the tail end of the groove III is too high, so that the coffee beans are easily damaged.

The utility model discloses a protection scope is not limited to this, also can be for a set of, three group or more than three groups, relatively speaking, and two sets of can guarantee the stable support to the groove, can reduce the requirement to the processing installation again, and the cost is lower simultaneously, and economic benefits is good.

A coffee bean transporting chute as described above, wherein the junction of the chute II with the chute I and the chute III is smoothly transited. The grooves are in smooth transition, so that the coffee beans can be prevented from being damaged at the joints of the grooves, and the coffee beans can be prevented from sliding out of the grooves.

The coffee bean conveying trough has the advantages that the trough I, the trough II and the trough III are the same in shape and size and are all U-shaped troughs. The protection scope of the present invention is not limited to this, and only a feasible technical solution is listed here, and the shape and size of the solution can be different, so long as it is ensured that the coffee beans can smoothly slide in the three grooves, and do not slide out of the grooves.

The coffee bean conveying groove has the advantages that the central axes of the grooves I and III are at the same included angle with the horizontal plane. The protection scope of the utility model is not limited thereto, and the included angle between the two, namely the gradient, can also be different.

The coffee bean conveying trough has the advantages that the length of the trough I is the same as that of the trough III, the length of the trough I is 20-30 cm, and the length of the trough I is 1.2-1.5 times that of the trough II. The grooves I and III are too long, so that the speed of the coffee beans at each section is too high, the pressure of the coffee beans at the filter screen is overstocked, or the landing speed of the coffee beans is too high, and the damage is caused; too short a length, too low a speed of the beans at each section, may affect the transportation speed or cause backlog of beans at the sieve.

According to the coffee bean conveying groove, the minimum distance between the filter screen and the groove I is 40-60% of the length of the groove II. The mounting position of the filter screen is too high, namely the minimum distance is less than 40% of the length of the groove II, the coffee beans are not accelerated in the groove II sufficiently, and the filtering effect of the filter screen on the coffee beans is influenced; the position of the filter screen is too low, the acceleration of the rear section of the groove II on the coffee beans is not enough, and the conveying speed is influenced. The mesh number of the filter screen is set according to actual requirements, and simultaneously the mesh number of the filter screen is matched with the quality of coffee beans to be conveyed, namely the coffee beans with the particle size smaller than the mesh number of the filter screen in the coffee beans to be conveyed are smaller than 5% of the total coffee beans.

The coffee bean transporting tank as described above, wherein the surface roughness Ra of the tank I, the tank II or the tank III is 0.2 to 0.4. mu.m. The surface roughness of the grooves is too large, so that coffee beans are easily scratched in the conveying process; the surface roughness is too small, the requirement on processing precision is too high, the economic benefit is not good, and simultaneously, the filter effect of the filter screen is influenced, and the gradient and the length of the groove need to be synchronously adjusted.
