Tomato skin, seed and residue dehydration drying and dry method skin and seed separation and combination production method in tomato paste factory

Abstract

The invention discloses a tomato skin, seed and residue dehydration drying and dry method skin and seed separation and combination production method in a tomato paste factory; the tomato skin, seed and residue obtained by pulping, peeling off and seed removal procedures in the tomato paste factory are used as raw materials, after wet skin, seed and residue are pre-dehydrated by adopting a squeezing method, a cocurrent rotary drum drier is adopted to dry the wet tomato skin, seed and residue with mixed skin and seed; and then a skin-seed rubbing dispersion device which is embedded between a material outlet of the drier and terminal dedusting equipment in series is adopted to separate the skin and seed; the separated skin is compressed to improve the density or high-pressure high-temperature disinfestation and sterilization is carried out to prepare into particles, and tomato seed crude oil and oil cakes are extracted from the separated seeds by adopting the equipment and technology in the existing vegetable oil plants, and the tomato seed crude oil is extracted only by degumming and deacidifying refining, in the way, the tomato skin, seed and residue can be processed in a large scale, so as to lead the comprehensive utilization of the tomato skin, seed and residue to realize industrial production; in addition, water does not need in the technology process, thereby greatly reducing the environmental protection of the tomato residue and completely eliminating the environment pollution of discharged waste water with high BOD and suspended matters in the technology of separating skin and seed with a wet process in the prior art; only degumming and deacidifying refining are carried out to the tomato seed crude oil, the decoloration and deodorization procedures in the deep refining are cancelled, so as to prevent oil rancidity, improve transparency and fully keep the commodity characteristics and nutritional components of the tomato seed oil.

Description

Technical field: [0001] The invention belongs to the technical field of fruit and vegetable processing, in particular to a combined production method of dehydrating and drying tomato peel and seed dregs in a tomato paste factory and separating dry peel and seed. Background technique: [0002] The production capacity of tomato paste factories in China has reached more than 1 million tons, and more than 7 million tons of fresh tomatoes are processed every year. In less than 60 days of production per year, tomato paste plants discharge about 400,000 tons of tomato pomace. Tomato skin and seed dregs contain a lot of water, are mixed and sticky, and are difficult to process. At present, there is a lack of productive complete technology, and the wet mixture is used as feed, fertilizer or discarded. [0003] In the prior art, a belt dryer or an airflow dryer is used for drying tomato skin and seed dregs. To solve the problem of separating the skin and seeds in the dregs, generally...

Problems solved by technology

However, the deficiency of the existing technology is that the energy consumption is too high, and the combination of drying and peel and seed separation procedures is not considered to comprehensively save energy, and it is difficult to realize the economical and la
