Description

The pre-disk stripping of the quincunx of evapo-separated machine

Technical field

The steaming that the utility model relates to the wet dregs of rice solvent of vegetable oil mill takes off and dries, and is specifically related to a kind of pre-disk stripping of quincunx of evapo-separated machine.

Background technology

Vegetable oil mill leaches the wet dregs of rice evapo-separated machine used in workshop and mainly contains high bed desolventizer toaster at present, the vertical type steaming off line, DTTC type evapo-separated machine, DTC type evapo-separated machine, above these several evapo-separated machines respectively have relative merits, high bed desolventizer toaster, the vertical type steaming off line mainly is applicable to the wet dregs of rice solvent of rapeseed meal and steams de-, DTTC type evapo-separated machine complex structure mainly is applicable to the above scale vegetable oil mill leaching of 1000T/D workshop soybean wet dregs of rice solvent and steams de-, applicable surface is wider comparatively speaking for DTC layer evapo-separated machine, be widely used in the following scale vegetable oil mill of 500T/D and leach the wet dregs of rice of workshop vegetable seed, the cottonseed wet dregs of rice, soybean wet dregs of rice solvent steams de-, there is energy consumption moderate, maneuverable characteristics, DTC type evapo-separated machine has absorbed the characteristics of DTTC type evapo-separated machine and high bed desolventizer toaster, many vegetable oil mills leach workshop and have all used DTC layer evapo-separated machine, but, because domestic oil plant moisture content is larger, the pre-pressed cake oil-containing is higher, after pre-pressed cake leaches, the wet dregs of rice are high containing molten amount, causing DTC type evapo-separated machine solvent to steam takes off endless, residual molten the exceeding standard of the dry dregs of rice, according to our investigation, in annual summer, although many vegetable oil mills leach the dish dregs of rice " blasting test is qualified " of workshop DTC type evapo-separated machine output, but dissolvent residual exceeds standard, often be greater than 700ppm, generally at 1000 ppm, maximum 2000 ppm, not only cause solvent consumption high, output and quality descends, also there is certain potential safety hazard, in summer in every year, when new vegetable seed listing is driven, often exist the evapo-separated machine solvent to steam and take off endless, although the dish dregs of rice " blasting test is qualified ", dissolvent residual exceeds standard, and dish dregs of rice color and luster is dark, during cottonseed, equally also there is the partially dark problem of cotton dregs color and luster in processing, causes the dish dregs of rice, cotton dregs appearance bad, and market price is on the low side, slack market.

The evapo-separated machine principle of work: the wet dregs of rice are in the pre-disk stripping of the first layer, and bed depth 150-200mm, be preheating to 60 ℃, and partial solvent starts vaporization, and solvent is removed 20% left and right; Enter again the pre-disk stripping of the second layer, bed depth 150-200mm, temperature reaches 70 ℃ of left and right solvents further vaporizes, and solvent is removed 50% left and right; Continue to enter the 3rd layer, bed depth 1000mm, utilize the steam distillation principle, to material, sprays into open steam, and add-on accounts for the 1-1.5% of material, and temperature reaches 80-85 ℃, and solvent purifies substantially, and dissolvent residual is below 700 ppm; The 4th layer, layer 5 are baking zone, and effect is to remove moisture content; Layer 6 is namely last one deck of cold wind layer, and the wet dregs of rice become the dry dregs of rice, moisture content≤12%, and blasting test is qualified, containing molten≤700 ppm, temperature≤60 ℃.

Summary of the invention

The purpose of this utility model is: a kind of pre-disk stripping of quincunx of evapo-separated machine is provided, solve the evapo-separated machine solvent steam de-ly not thorough, residually moltenly exceed standard, problem that dregs of rice color and luster is partially dark.
