Dehydrating and dry method skin seed discrete group combination production method of a kind of catsup factory's tomato skin seed slag
Technical field:
The invention belongs to the garden stuff processing technical field, the dehydrating and dry method skin seed discrete group combination production method of particularly a kind of catsup factory's tomato skin seed slag.
Background technology:
The catsup factory production capacity of China has reached more than 1,000,000 tons, and annual processing fresh tomato is more than 7,000,000 tons.Catsup factory every year less than 60 days production in, discharge about 400,000 tons of tomato skin seed slags.Tomato skin seed slag is moisture many, mixes bonding, is difficult to processing, lacks productivity set technique technology at present, is in the hygrometric state mixture is made feed, fertilizer or discarding state.
In the prior art,, the skin seed in the slag is separated a difficult problem, in water, separate the skin seed behind the general first thin up tomato skin seed slag, dehydrate the also employing CO that has after the wet separation dry band drier or the pneumatic drier of adopting of tomato skin seed slag
2Supercritical extraction unit extracts, purifying.But it is too high that the shortcoming of prior art is energy consumption, all do not consider drying and skin seed separable programming are made up and synthesis energy saving, is difficult to realize economy, the scale suitability for industrialized production of tomato skin seed slag.Cause over nearly 15 years, a large amount of valuable compositions are arranged, produce yet and utilize although people know in the tomato skin seed slag that catsup factory discharges.
Summary of the invention:
The objective of the invention is, dehydrating and dry method skin seed discrete group combination production method of a kind of catsup factory tomato skin seed slag is provided, can solve the industrial problems that tomato skin seed slag for comprehensive utilizes.
Technical scheme of the present invention is that dehydrate and the dry method skin seed discrete group combination production method of tomato skin seed slag comprise:
The tomato skin seed slag that goes the seed operation to discharge with the making beating of catsup factory is a raw material, and wet tomato skin seed slag adopts spiral press dewatering, makes its moisture content from more than 75%, drops to below 65%.Adopt the wet tomato skin seed slag of the dry skin seed of downflow type whizzer mixing shape then, whizzer has three layers of rotating cylinder, the rotating cylinder inwall all has the bowl-type flight of spiral layout, when drying machine rotates, material is taken up in the bottom, be scattered down by throwing to top, advance by setting path simultaneously.Skin in taking up the process of shedding in the tomato pomace and seed major part from.Tomato skin is easily dried and proportion is less, walks fast in hot blast, and drying time is short; Otherwise, tomato seed or skin seed grume be difficult do and proportion bigger, in hot blast, lose time, drying time is long.This drying machine is convenient to adjust the rotating cylinder rotating speed according to tomato pomace treating capacity, hot blast temperature and air quantity, can determine technological parameter by the operative employee according to the input and output material situation at any time.
Utilize the embedding skin seed of between drying machine discharging opening and terminal cleaner, connecting to rub discrete device afterwards, skin in the binding material fritter after the drying and seed are rubbed scattered, make the distinguished and admirable skin seed that has separated of carrying secretly enter the fractional sedimentation chamber, compartment of terrain, expansion chamber top is provided with plate washer, forces the landing of seed and skin bump.The cross section of expansion chamber makes wind speed gradually low after by forward direction.The volume leading portion part of expansion chamber is little, and back segment part is big, so that accept the tomato seed and the tomato skin of weight such as apparent gravity is different and basic respectively.
Isolated dry tomato skin improves density with the frame hydraulic press compression or with the granulation of ring mode comminutor, finishes pesticide-germicide simultaneously and improve density.
In to isolated tomato seed crude oil refining process, in order to keep beta carotene and the lycopene in the tomato seed oil, only it is carried out press filtration, comes unstuck and depickling, do not carry out decoloration and deodorization.To the tomato seed oil of transparent inner wrapping, take lucifuge trapping packing, as overcoat carton, dark plastic sheeting or aluminium-foil paper, and low temperature preserves, and prevents from that illumination and oxidation from causing to fade or rotten.
The invention has the advantages that: implementing the present invention can large-scale processing tomato skin seed slag, make the comprehensive utilization of tomato skin seed slag realize suitability for industrialized production, and water not in the technical process, not only significantly reduce the environmental pollution that wet tomato pomace itself causes, and eliminate the pollution of the high BOD that produces in the prior art wet separation skin seed technology and high suspended matter discharge of wastewater fully environment.
The specific embodiment:
Embodiment one: the tomato skin seed slag that goes the seed operation to discharge with the making beating of catsup factory is a raw material, adopts expeller to dewater in advance, makes its moisture content from more than 75%, drops to below 65%.Dehydration back wet feed enters the whizzer drying, and drying machine provides hot blast by coal-fired hot-blast stove.The rotating speed of whizzer is 0~10 rev/min of adjusting; Material is 30~50 minutes tube inner drying time, volume of material take up space volume 10%~20%/.Utilizing between drying machine discharging opening and terminal cleaner series connection to embed the skin seed then rubs discrete device and separates the skin seed, skin in the binding material fritter after the drying and seed are rubbed scattered, make the distinguished and admirable skin seed that has separated of carrying secretly enter the fractional sedimentation chamber, it is integrated to realize that the skin seed separates with drying process.It can be the pulverizer shape that the tomato skin seed is rubbed discrete device, but awl hits and hold in both hands or the sheet rotating speed is controlled at and makes the excellent sheet can complete centrifugal stretching, extension, is lower than 1400 rev/mins; Air inlet through hollow shaft and material, radially or tangential direction air-out and material; Charging can be enterprising formula, also can be side-feeding type.When the tomato skin of separating is made feed, tomato skin with the granulation of ring mode comminutor, is produced under the hot conditions at high pressure, make tomato skin finish the pesticide-germicide effect, make the apparent gravity of skin particle improve more than 5 times than diffusing shape dry hide.Make lycopene raw material etc. in particular cases in tomato skin, only use hydraulic press briquetting, not high pressure granulation.In the isolated tomato seed crude oil refining process,, only it is carried out press filtration, comes unstuck and depickling, do not carry out decoloration and deodorization in order to keep beta carotene and the lycopene in the tomato seed oil.To the tomato seed oil of transparent inner wrapping, take lucifuge trapping packing, as overcoat carton, dark plastic sheeting or aluminium-foil paper, and low temperature is preserved.
Embodiment two: compare with embodiment one, dewater in advance without expeller, and dewater with belt press.
Embodiment three: compare with embodiment one, tomato skin is used the hydraulic press briquetting without ring mode comminutor compressed granulate, or directly makes commodity selling.
Embodiment four: compare with embodiment one, the tomato seed does not extract grease and directly makes commodity selling.
Embodiment five: compare with embodiment one, the multicell expansion chamber changes tandem cyclone separator group into, and prime is isolated seed, and the back level is isolated skin.
Embodiment six: compares with embodiment one, and the embedding of between drying machine and skin seed expansion chamber, not connecting of skin seed discrete device, and be arranged in parallel with it.The skin seed compound that expansion chamber is collected when taking advantage of the drying machine shutdown, is sent into expansion chamber again and is isolated seed and skin after skin seed discrete device is handled.
Embodiment seven: compare with embodiment one, coal-fired hot-blast stove changes combustion gas or warm air oil furnace into.
