A can of diced tomatoes

Abstract

The invention discloses a method for preparing canned diced tomatoes. The method specifically relates to raw material inspection, pre-washing drifting separation, a scraper type high-altitude lifting machine, an overhead storage tank, raw material selection, tomato washing and sorting in a bubbling tank, scald peeling, dicing and sorting, tin can inspection, a breaking system, preheating and softening enzyme deactivation, refining and pulping, vacuum concentration, pre-sterilization, juice and dice canning, a heating power exhaust system, filling and sealing, heat sterilization with boiled water, packaging, standing and checking, and storage and transportation. During scald peeling, peels are cured through high-temperature steam and then delivered to a vacuum section for condensation so as to shrink, crack and fall off, and tomatoes subjected to steam scald peeling are rubbed and rotated through rollers so that peels can completely fall off. According to the method, during peeling, after high-temperature steam scalding, tomatoes are rubbed and peeled through the rubber rollers, so that the effects of quick peeling, tomato integrity, and lycopene loss reduction are realized, fully-automatic mechanical continuous production is achieved, labor intensity is relieved, product competitiveness is improved, and market share is increased.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a can of diced tomatoes. Background technique [0002] With the rapid development of the world economy, the acceleration of people's life rhythm and the change of concept, tomato products are gradually becoming a must-have food on people's table. According to data, the tomato raw materials used for processing tomato products in the world reach more than 30 million tons every year, far exceeding the output of 10 million tons of fresh tomatoes. [0003] my country's tomato processing industry is mainly concentrated in Xinjiang. The tomato processing volume has reached 7 million tons, and the output of products has exceeded 1 million tons. In recent years, the tomato planting area in Xinjiang has continued to expand, and the output of tomato paste has also continued to increase. industry chain. Although Xinjiang is the largest tomato processing area in the country, and the ...

AI Technical Summary

Problems solved by technology

Although Xinjiang is the largest tomato processing area in the country, and the tomatoes produced are of good quality, most of them are still engaged in the rough processing of tomato paste. The technology is mature and the variety is single, which cannot meet the needs of multiple varieties in the international market. The rich nutrients in tomatoes are lost. And it is prone to microbial contamination, and the concentration and sterilization time are long, which will affect the quality, color and nutrients of the product

It is easy to lose the original freshness of tomato
