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 large-scale industrial production of tomato peel and seed dregs.
Cause nearly 15 years, although people all know that there is a large amount of valuable composition in the tomato husk seed residue that tomato paste factory discharges, still haven't produced and utilized

Embodiment 1

[0011] Embodiment 1: Using the tomato peel and seed residue discharged from the beating, peeling and seed removal process of a tomato paste factory as raw material, a screw press is used for pre-dehydration, so that its moisture content is reduced from more than 75% to less than 65%. After dehydration, the wet material enters the rotary drum dryer for drying, and the dryer provides hot air from a coal-fired hot air stove. The rotating speed of the rotary drum dryer is adjusted at 0-10 rpm; the drying time of the material in the drum is 30-50 minutes, and the volume of the material occupies 10%-20% of the space volume. Then use the skin and seed kneading and discrete device embedded in series between the outlet of the dryer and the terminal dust removal equipment to separate the skin and seeds, and rub the skin and seeds in the small pieces of the dried bonded material, so that the air flow entrains the separated skin and seeds into the The subsection settling chamber realizes ...

Embodiment 2

[0012] Embodiment two: compared with embodiment one, dehydration is not carried out with a screw press, but with a belt press.

Embodiment 3

[0013] Embodiment 3: Compared with Embodiment 1, the tomato peels are not pressed into granules by a ring mode granulator, but are briquetted by a hydraulic press, or directly sold as a commodity.

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...
