A coffee bean cleaning and grading equipment

Abstract

The invention belongs to the field of coffee bean processing equipment, and particularly relates to coffee bean cleaning and grading equipment. The coffee bean cleaning and grading equipment comprises a basic structure, an S-shaped grading tank, a first-stage discharge tank, a second-stage discharge tank, a water inlet pipe, soaking pools and blanking pipes, wherein a plurality of soaking pools are arranged beside the basic structure, the blanking pipes are respectively arranged on the soaking pools, the S-shaped grading tank is arranged on the basic structure, so as to form a blocking layer on the basic structure, the water inlet pipe is arranged on the first-stage grading tank of the S-shaped grading tank, the third-stage grading tank of the S-shaped grading tank is led to the outside of the basic structure, and the first-stage discharge tank and the second-stage discharge tank are arranged on the third-stage grading tank of the S-shaped grading tank in sequence. According to the coffee bean cleaning and grading equipment, cleaning and grading are integrally processed, so that the processing steps are reduced, and the processing efficiency is improved; the coffee bean cleaning and grading equipment has the advantages of simple structure, low manufacturing cost, convenience in operation, good cleaning effect, high unqualified bean grading rate, low maintenance cost and no consumption of electric energy; the coffee bean cleaning and grading equipment satisfies various requirements of a coffee bean processing plant and is easy to widely favor; the quality of finished products is guaranteed; the processing cost is reduced.

Description

technical field [0001] The invention belongs to the field of coffee bean processing equipment, and in particular relates to coffee bean cleaning and grading equipment. Background technique [0002] Cleaning and grading are necessary steps in coffee bean processing. At present, there are two ways to realize coffee bean cleaning and grading in coffee bean processing plants, which are cleaning tank cleaning and grading and mechanical cleaning and grading. The cleaning tank cleans and grades the coffee beans, removes the stains on the surface of the coffee beans by manual stirring, and then separates the defective beans such as mildew and empty shells mixed in the coffee beans by flotation. However, this method has low work efficiency, large artificial labor force, inconvenient bean extraction, and low bean grading rate, which affects the overall quality of finished products. Mechanical cleaning and grading are accomplished jointly by the cleaning device and the grading device...

AI Technical Summary

Problems solved by technology

However, this method has low work efficiency, large human labor force, inconvenient bean extraction, and low grading rate of inferior beans, which affects the overall quality of finished products.

Mechanical cleaning and grading are completed jointly by the cleaning device and the grading device. The two devices work independently, which increases the process steps and complicates the cleaning and grading

Moreover, the structure of the cleaning device and the grading device is complicated, the manufacturing cost is high, the maintenance is difficult, the cost is high, the energy consumption is large, and the processing cost is increased.
