Description

A multifunctional small emblica screening machine and its application method

technical field

The invention relates to a screening machine, in particular to a multi-functional small emblica screening machine and a using method thereof.

Background technique

Emlical fruit is mainly produced in the southeast coast, such as Fujian, Taiwan and other places. The fruit has a unique flavor and is rich in nutrition. The fruit of emblica is oblate, and the diameter of mature emblica is about 2~3cm. It can be eaten raw, but it is generally eaten after pickling because of its bitterness. It can also be used to make candied fruit, candy, candied haws, etc. There are many emblical fruits planted in the southern part of Fujian Province. In recent years, many emblical processing factories and small workshops have sprung up to process emblical fruit and make preserves and candies. Before processing emblica, it is necessary to carry out pre-processing treatment on emblica. Usually, processing shops and small workshops will purchase raw emblica from fruit farmers. The emblical fruits picked by fruit farmers usually have fruit leaves, branches or fruit residues, and the emblic fruit particles are of different sizes. At the same time, when purchasing, the prices are often differentiated according to the particle size of emblica and the color of emblica. Therefore, for fruit growers, it is necessary to screen emblical fruits for grain and fruit color in order to sell them at a good price; for processing factories and small workshops, when processing emblical fruits, firstly, impurities need to be removed. And further particle screening is required.

At present, there are some automatic fruit screening machines on the market. These machines have single functions and can only perform simple impurity removal or screening functions. Moreover, the equipment is large in size and expensive, and cannot meet the needs of ordinary fruit farmers and small processing workshops. However, most of the small processing workshops and fruit growers screen and remove impurities from emblica by hand or with simple sieves. The screening process requires a lot of manpower and time, and the efficiency is low and the screening is incomplete. Therefore, considering that there is no small-scale screening machine completely aimed at the characteristics of impurities of emblica and fruit screening requirements on the market, it is necessary to design a multi-functional small-scale screening machine for emblica.
