Abstract

A method for comprehensive utilization of tomato's peel and seed dregs features that wet and dry processes are used to separate the peel and seed from its pulp. The separated peel and seed dregs are made into tomato peel particles, tomato seed oil and feed.

Description

The production method that skin from ketchup factory seed slag for comprehensive utilizes

The invention belongs to the garden stuff processing technical field, be applied to skin from ketchup factory seed slag and produce the tomato skin particle, the dried dregs of rice of tomato seed oil and feed.

Present domestic tomato ketchup production capacity has reached about 150,000 tons/year, the about 90-100 ton of processing fresh tomato/year, about 100,000 tons of year discharging skin seed waste residue.If the scrap leather seed comprehensive utilization that tomato ketchup factory is discarded in a large number makes it to become easy storing, the feed that the market demand is big, edible health oil, skin also can be used as the new source of extracting the natural food-pigment of red rice raw material.Now a large amount of discarded skin seeds do except that being pulled away by the peasant in a small amount that major part still is not utilized feed or the fertilizer, still do not have industrial processes, the serious environment that polluting.

Purpose of the present invention provides a kind of skin from ketchup factory seed slag to produce the tomato skin particle, the production method of the tomato seed oil and the dried dregs of rice of feed.

Purpose of the present invention can realize by following measure: the tomato skin seed slag that goes the seed operation to discharge with the making beating of tomato ketchup factory is a raw material; be used for directly making product or system particle or briquetting after wet method or dry method are separated the skin seed; seed is characterized in that with squeezing and the oil and grease extracting and the dried dregs of rice of feed:

A. tomato skin seed slag being added water more than ten times mixes and to pump into cyclone hydraulic separators after stirring evenly and utilize the different principle of skin seed centrifugal force to separate skin and seed.

B. tomato skin seed slag is placed on different skin and the seeds of separating of the proportion buoyancy that utilizes the skin seed in the pond.

C. utilize disintegrating machine to break up after the tomato skin seed drying and use pneumatic separator again, utilize skin different, separate skin and seed with the proportion of seed.

D. behind the tomato skin humidification with spiral Squeezinggranulator granulation.

E. touch compound stalk forming in the frame with spiral shell dry type forcing press behind the tomato skin humidification.

F. adopt pressafiner and solvent extraction to extract the edible tomato seed oil and the dried dregs of rice of feed by above-mentioned wet method and the isolated tomato seed of dry method.

Advantage of the present invention is: scrap leather seed slag one is become the skin particle, dried dregs of rice powder and oil.Increase economic efficiency greatly, open up new production approach, improve environmental pollution.Feed is convenient to storing, and livestock easily digests and assimilates.Tomato seed oil is the high-quality edible oil of favourable health care, increases new oil sources.

The invention will be further described below in conjunction with embodiment.

Embodiment 1: place the making beating of tomato ketchup factory to remove seed skinning machine conveying worm skin seed outlet in automobile, roping is spread out to cement floor, stack 2-5 centimetre of thickness, per 5 tons of waste residues spread out 100-300 square metre on ground approximately, the thin more drying of thickness at stand is fast more, it is fast more to stir many more dryings, in Xinjiang about 3-6 days seven to September can be dried to moisture below 13% or hand rubbing can make skin seed released state.Handling 25 tons of waste residues day needs cement to mix 5000 square metres on earth threshing ground approximately, with about 25 people of casual labour.Dried waste residue is big or small uneven lumps.With little other pulverizers of feed grinder or degree of grinding or stone grinds or steel mill and so on machinery is dispersed as independently and evenly sends into winnowing machine or winnowing machine behind the skin and grain seed, seed is heavier to be fallen earlier with dried waste residue, and skin is gentlier blowed far away by wind, separate seed and skin according to this.Handle 25 tons of waste residues day and get each about 3.5 tons of dry hide and seeds approximately.Dry hide can be in bulk or the sale of dispatching from the factory of dress gunnysack or woven bag.Also can be lowered to spiral feed granulator or hops granulator extruder grain,, be convenient to store and transportation so that it is about 50% to save packing in the condition of water content 10 ± 3%.Dried seed water content is controlled at 10 ± 3% interim storages, being transported to oil-fat plant cleans earlier by vegetable seed oil extracting process and machinery, rerolling feed, go into 95 types immediately after steam frying or 200 type oil presses give press for extracting juice, oil yield is about about 10%, leaches greases with No. nine solvent light petrols again, reclaims solvent, dried seed oil-containing 17-27%, total oil yield is 15-25%.Day handle 25 tons of waste residues, approximately dried seed 3.5 ton per days, in 100 days/year 350 tons of dried seeds, can get oily 50-60 ton, oil meal 250-280 ton.Whether oil can do refining according to customer requirements, as do general feeds with oil or industrial soapmaking system oil can not refining.As do edible then to carry out no specific (special) requirements by the cottonseed oil refining process of maturation.Oil meal contains crude protein＞30%, can reach more than 35%, is that the feed primary raw material also can directly be made feed.

Embodiment 2: use level ground, compacted soil meadow or upper berth, level ground, soil Polywoven Bag instead except that daylight teds the place, outside the assorted material of anti-native stone such as Polypropylence Sheet was made, other modes of production were constant, removed the finished product ash content and improved, outside the place lost of life and how much difference of recruitment, the result is approximate.

Embodiment 3: adopt other industrially drying machineries as band drier, pneumatic drier is dry waste residue means, and back operation is substantially the same manner as Example 1, and cost is increased, and personnel selection reduces, and hygienic quality improves, and finished product yield is close.

Embodiment 4: adopt reinforcing bar to mix earth pond or steel pond, waste residue is gone into 100 cubic metres of ponds, pond about 10 tons in waste residue in the pond, water is The more the better.Upper strata emersion skin, lower floor's seed that avales, the skin seed teds or mechanical drying with daylight after separating again, and operation is with embodiment 1 thereafter.

Embodiment 5: adopt steel plate system cyclone hydraulic separators, waste residue added water more than 10 times, pump into tangential inlet at a high speed with centrifugal sewage pump, the adjusting flow stream velocity and up and down outlet to reach best skin seed separating effect.The skin seed dries or dries after separating, and operation is identical with embodiment 1 thereafter.

Claims (1)

1. the production method of skin from ketchup factory seed slag for comprehensive utilization is: the tomato skin seed slag that goes the seed operation to discharge with the making beating of tomato ketchup factory is a raw material; after being used for wet method or dry method separation skin seed; dry hide is directly made product or system particle or briquetting; seed is characterized in that with squeezing and the oil and grease extracting and the dried dregs of rice of feed:

A. tomato skin seed slag being added water more than ten times mixes and to pump into cyclone hydraulic separators after stirring evenly and utilize the different principle of skin seed centrifugal force to separate skin and seed.

B. tomato skin seed slag is placed on different skin and the seeds of separating of the proportion buoyancy that utilizes the skin seed in the pond.

C. utilize disintegrating machine to break up after the tomato skin seed drying and use pneumatic separator again, utilize different skin and the seeds of separating of skin with the proportion of seed.

D. behind the tomato skin humidification with spiral Squeezinggranulator granulation.

E. touch compound stalk forming in the frame with spiral shell dry type forcing press behind the tomato skin humidification.
