Intermittent spiral squeezing device and fruit and vegetable cold squeezing equipment

Abstract

The invention discloses an intermittent spiral squeezing device and fruit and vegetable cold squeezing equipment, and relates to the field of food processing equipment, in particular to improvement of a fruit and vegetable juicing device. According to the intermittent spiral squeezing device and the fruit and vegetable cold squeezing equipment, the crushing and shearing efficiency is high, the friction heat generation condition of materials and metal parts in the pushed process can be reduced, the whole processing process is in a cold state, and then effective components in fruits and vegetables are prevented from being volatilized and oxidized. The intermittent spiral squeezing device comprises a main shaft, a conveying and extruding screw arranged on the main shaft and a screen cylinder covering the conveying and extruding screw, and is characterized in that the conveying and extruding screw sequentially comprises a feeding and conveying screw section and at least two stages of squeezing screw sections from front to back, the squeezing screw sections and the feeding and conveying screw section are arranged in a disconnected manner, and the adjacent squeezing screw sections are arranged in a disconnected manner; and all stages of squeezing screw sections are arranged at intervals in the axial direction of the main shaft, and the screw pitches are gradually reduced.

Description

technical field [0001] The invention relates to the field of food processing equipment, in particular to the improvement of a fruit and vegetable juice extraction device. Background technique [0002] With the improvement of people's living standards, in order to take in vitamins and other nutrients, people are often used to eating a lot of fruits and materials. In order to better absorb vitamins and other nutrients, and efficiently digest and absorb them, drinking fruit and vegetable juices has gradually become a way of eating. Drinking the freshly squeezed juice directly requires very little digestive energy and can be completely absorbed by the body in just 15 minutes. Therefore, it is necessary to have special equipment to efficiently squeeze fruits and vegetables, and then carry out subsequent deployment to obtain fruit and vegetable juices with good taste, high yield and good quality. [0003] Such as CN 107713700 A, a patent application document for a screw juice ex...

AI Technical Summary

Problems solved by technology

However, there are the following problems in practical applications: First, when a single screw conveys materials, it will cause continuous frictional contact between the materials and metal parts (such as the surface of the screw, the surface of the shaft, and the surface of the screen cylinder, etc.), resulting in the friction of the material at the contact point. Increased temperature will lead to the decomposition and oxidation of active ingredients in fruits and vegetables

Second, when there are fruits and vegetables with long fibers (such as 1-10cm) (such as oranges, citrus, sugar cane, cabbage, celery, etc.), it is difficult for the equipment in this case to effectively cut the fibers, resulting in easy congestion of residues

Third, the crushing efficiency is not high
