Description

A kind of wet dregs of rice evapo-separated machine
Technical field
The present invention relates to a kind of wet dregs of rice evapo-separated machines.
Background technique
In oil extraction oil factory, the dregs of rice through draining naturally come out from infuser, generally all the solvent containing 25%-35% and A certain amount of moisture.The content of solvent in the dregs of rice, containing molten referred to as in the dregs of rice, and the dregs of rice containing solvent and moisture are referred to as the wet dregs of rice.It will be molten The process that agent is removed from the wet dregs of rice is known as wet dregs of rice precipitation on oil prodution industry.The main method of solvent removal is to steam to take off in the wet dregs of rice, The solvent of the wet dregs of rice must all be evaporated, be reused after condensing recovery, economically rationally could could maintain production, will Solvent contained in the wet dregs of rice reduces as far as possible, the height to oil extraction plant management and technical level be it is marginal, because of the dregs of rice In containing the molten low reduction for meaning that solvent loss, it is safer in the storage and transportational process of the dregs of rice.For setting for wet dregs of rice precipitation Standby is evapo-separated machine, has the double action that solvent steams the drying of de- and moisture concurrently.And it sloughs solvent and is reduced to water content therein The dregs of rice of safe moisture, the then referred to as dry dregs of rice.Wet dregs of rice precipitation technique, according to the different and different of dry dregs of rice purposes.Usually it is made for feed The dregs of rice, to destroy animal antinutriment, antinutritional factor therein, often using the precipitation technique under wet heat condition, i.e., conventional precipitation technique;And The precipitation technique under lower temperature then can be used for the denaturation for preventing wherein protein as the dregs of rice for extracting protein product raw material, That is low temperature desolventizing technique.The purpose of wet dregs of rice precipitation is that, according to the requirement to the dregs of rice, is removed fully and completely as far as possible Remaining solvent in the wet dregs of rice, and the moisture of the dregs of rice is adjusted accordingly, so that the quality of the dregs of rice reaches the set quota.And it removes The complexity of residual solvent is related with existence of the solvent in the dregs of rice in the wet dregs of rice.
Removing the common method of solvent in the wet dregs of rice is so that the solvent in the wet dregs of rice is obtained thermal energy and is vaporized by means of heating, from And it is separated with the dregs of rice.It is this to be known as solid in chemical industry from the operation for removing hygroscopic water (solvent or moisture) in solid material by means of thermal energy Drying, and the steaming for being then known as the wet dregs of rice in vegetable oil mill is de-, but solvent steams de- process in the wet dregs of rice and the difference of drying process exists In: drying is just to finish when reaching certain material structure moisture, and steaming de- purpose is sufficiently to remove to the maximum extent Solvent.It is steamed in de- operation in the wet dregs of rice, solvent is that surface is diffused into inside the wet dregs of rice, then re-vaporizes and is transferred in gas phase.Institute It is the mass transport process that a solvent is transferred to gas phase from solid phase on the process nature taken off with the steaming of the wet dregs of rice.
The precipitation of the wet dregs of rice is that solvent steams de- process and is made of two stages with drying process similarity: constant speed is evaporated It is evaporated with reduction of speed.When precipitation starts, solvent is evaporated from dregs of rice grain surface, and in this stage Shen, main removal is in non-knot with the dregs of rice The solvent of conjunction state.Thus separation is easier, this stage is the first stage of precipitation --- constant rate period;And work as evaporating surface After going deep into inside particles, mainly inside particles and the dregs of rice are in the separation of the solvent of bonding state, therefore carrying out for this stage is ratio More difficult.This is the second stage of precipitation --- falling-rate period.In order to strengthen precipitation effect, answered in wet dregs of rice desolvation process So that dregs of rice grain is in state of ceaselessly stirring, and improves rate of heat transfer as far as possible.As suitably reduced solvent vapour in surface of material again Partial pressure, then be more advantageous to the removal of solvent in the dregs of rice.Therefore current wet dregs of rice precipitation technique, generallys use stirring and open steam It is used in combination with indirect steam, or even reaches comparatively ideal precipitation effect with means such as vacuum.In order to guarantee to the maximum extent sufficiently Steam desolventizing, it is necessary to improve the temperature for steaming de- process, but cause high temperature action that will cause protein when moisture in removing the dregs of rice Excessive denaturation so that nutritious amino acid in conjunction with other substances in the dregs of rice, can thus make the feed value of the dregs of rice Declined, thus reduce the quantity of the protein of effective nutritive value in the dregs of rice, it is therefore necessary to during guaranteeing that steaming is de- as possible Protein is kept not to be denaturalized excessively to the maximum extent.
Modern steaming desorption method can be divided into following form: (1), steaming of the solvent in stirring layer it is de-;(2), the wet dregs of rice are in portion Divide the steaming of part stirring thing material under suspended state de-;(3), steaming of the wet dregs of rice under suspended state is de-.Wherein, (1) and (2) class Desolventizing method belongs to conventional precipitation technique, and the dregs of rice of feed are used as in production;And (3) class desolventizing method belongs to low temperature desolventizing technique, The raw material of food vegetable protein is made in production.The wet dregs of rice desolventizing equipment of this patent is to belong to (1) class desolventizing method.

(2), the steaming of wet dregs of rice stirring thing material in part under partial suspended state is de-, and the de- dregs of rice are steamed mainly in horizontal evapo-separated machine Contained solvent.The advantages of horizontal evapo-separated machine is: power consumption is few, easy to operate.The disadvantage is that: consumption steel are more, shaft end seal Performance is poor, and the dregs of rice end of entrained with is more in mixed vapour;The ability for being passivated noxious material and anti-nutrient substance is weaker;With vertical type steaming Off line is compared, all poor in terms of precipitation baking and detoxification effect.
(3), steaming of the wet dregs of rice under suspended state is de-, mainly in the flash distillation desolventizing equipment of low temperature desolventizing technique.Flash distillation is de- The advantages of molten evapo-separated machine, is: because to the time of wet dregs of rice heat effect very short (generally 2 seconds), therefore albumen in the low denaturation dregs of rice after precipitation Qualitative change is seldom, is the raw material for producing various food plant protein products.The shortcomings that flashing precipitation evapo-separated machine is: after precipitation, It cannot be guaranteed that fully removing solvent in the dregs of rice, and still containing the residual solvent (2%~5%) for having more than permission limit in the dregs of rice, it is necessary to It further processes under vacuum or with superheated steam.
It is energy-saving to be with advances in technology with the development of social economy, and the environmental protection and the pressure of resource that face One important trend of the research and development of vegetable oil processing technology and equipment, the R&D direction for leaching wet dregs of rice precipitation are how to reduce steaming How vapour consumption improves the economic and technical norms etc. of equipment production, is the main path for reaching energy-saving this purpose.
