Description

Litchi meat collection device

Technical Field

The utility model relates to a litchi processing equipment technical field, specifically speaking relates to a collection system of litchi meat.

Background

With the continuous development of farm product deep processing, at present, fully automatic production equipment does not exist in litchi deep processing, only some semi-automatic machines peel and then remove cores, and the juice in the flesh can be squeezed away due to peeling by an extrusion method. The pits are ellipsoidal, smooth in surface, different in size and crisp in texture, the long axis is wrapped in the middle along the growth direction of the pedicles, if the pits are not positioned well, appearance cracking can be caused, and the deep processing quality of the litchi is seriously affected.

At present, the following two methods are generally adopted when dried lychees are made:

1. traditional solarization: when the method is adopted to produce the dried litchi, the fresh litchi cut with the spikes is uniformly arranged in a bamboo plaque, is insolated in the burning sun until the dryness reaches seven-eight, is piled up and is covered by a jute bag to be remoistened, so that the inside and the outside of the pulp are uniformly dried. And after softening, the fruit shells are continuously exposed to the sun, when the fruit shells are dried to eighty-nine days, the fruit shells fade, and the fruit shells turn red by spraying a small amount of water by a sprayer in the burning sun. The production cycle of the dried lychee made by the method is as long as 20-25 days. In addition, during the drying and exposure process of the litchi, a lot of flies are attracted to stay on the litchi, so that the produced dried litchi is not sanitary. The shape of the finally dried litchis is different and the litchis are not sold well.

2. Semi-automatic pitting method: when the method is adopted to manufacture dried litchee, the templates are manually selected according to different shapes and diameters of the litchee, and the litchee are poured into the storage hopper, so that the feeding and conveying effects are achieved, the litchee are brushed into other holes through the hairbrush, the positioned litchee are continuously conveyed and pushed, the litchee are subjected to kernel flushing by using the process of the machine tool in the conveying and pushing process, kernels fall into the kernel-discharging dustpan and automatically flow out and are collected together, the litchee which have flushed through the kernels are continuously conveyed to the next link to automatically fall off, and the litchee fall into the dustpan and automatically flow out and are collected together, so that the litchee and the kernels are separated.

However, the bottleneck of removing the core is still not solved well, so that many companies do not professionally process other fruits after dealing with the processing.
