Abstract
The invention relates to a process method for grease desoaping, which comprises the following steps: inputting soybean oil subjected to alkali refining into a desoaping centrifuger to remove most of soapstock; then adding a certain amount of spent bleaching earth used as adsorbent into the oil, and evenly mixing; and performing centrifugal separation on the materials at appropriate stirring speed, adsorption temperature and adsorption time, thus obtaining oil to be bleached. The process method is mainly characterized in that the spent bleaching earth is used as the adsorbent to perform desoaping, and the soap content of the ultimate desoaped soybean oil is 24.10 mg/kg. Compared with the conventional desoaping through water washing, the grease loss in the water washing process is reduced, the spent bleaching earth is reutilized, and the consumption of the bleaching earth in the grease bleaching process is decreased.
Description
Technical field
The present invention relates to a kind of method of taking off soap technology, belong to food oils refining techniques field.
Background technology
The method of grease-decolor is a lot, at present the main atlapulgite that uses in the industrial production.Carclazyte after the decolouring becomes beige earth shape, loses activity, and can not remake discoloring agent and becomes useless carclazyte.Useless carclazyte generation is generally 1% ~ 5% of grease treatment capacity.Yet; The utilization again of useless carclazyte is a problem demanding prompt solution always, and general grease factory all abandons it or landfill as refuse, and so not only useless carclazyte is not fully used and has been wasted resource; Increased the plant produced cost; The useless carclazyte that is not reclaimed simultaneously and utilize also pollutes the environment, and jeopardizes underground water, even the danger that causes fire is arranged.In addition, be adsorbed with 20% ~ 50% also waste for no reason of grease in the useless carclazyte.Along with the enhancing of human environmental consciousness, the domestic and international at present processing to useless carclazyte mainly comprises following several respects: from useless carclazyte, extract oil content, as the molding sand additive; Produce the 4A molecular sieve, make cement or brick, do organobentonite; Produce scrubbing powder, make sorbent material etc. after the activation.Wherein, make sorbent material after the activation and mainly comprise the chromium that removes in the aqueous solution, remove the agricultural chemicals 2-first-4 chloro-phenylium in the sewage, Congo red etc. in hair plam oil decolouring and the adsorbed fuel waste water.
The conventional fat refinery practice must adopt appropriate means to remove soap stock behind alkali refining, carries out smoothly with what guarantee to decolour.Factory generally adopts washing step to reduce residual soap in the oil; And all the time the most unmanageable waste water of grease processing enterprise also derive from refinery wash soap waste water, the discharging that reduces or eliminates refining wastewater through new technology, technology is the problem that China's oils industry is being studied always.
At present, oils industry is released the anhydrous soap novel process of taking off both at home and abroad, and soap takes off with silica gel adsorption in the companies such as U.S. Jia Ji and ADM that mainly contain, and some grease enterprises of China also utilize zeyssatite and mixed adsorbent to take off soap.The present invention and its difference are to take off soap with useless carclazyte as sorbent material.Thereby the useless carclazyte that had both solved after the decolouring of grease processing enterprise can not get cope well, utilizes few problem again, has reduced the consumption of sorbent material such as carclazyte in the oil and fat refining process again, reduce cost, and be the method that a kind of effective grease takes off soap.
Summary of the invention
The present invention is directed to the defective of existing processing condition, a kind of usefulness method that useless carclazyte takes off soap as sorbent material is provided, the useless carclazyte after decolouring with solution grease processing enterprise can not get the problem of cope well, and the unmanageable problem of refining wastewater.Because the grease that adsorbs in the useless carclazyte is in state of saturation, takes off and has reduced greasy loss in the soap process.Take off finally behind the soap that saponified matter content is 24.10mg/kg in the VT 18.The useless carclazyte that takes off behind the soap can continue to recycle and reuse, and this method makes full use of resource, improves the quality of products, and reduces production costs, and obtains the more excellent soap technology of taking off.
Useful point of the present invention is:
The present invention utilizes useless carclazyte to take off soap as sorbent material; Reduced oil loss in the water washing process, and useless carclazyte has been utilized again, also had certain adsorptive power because useless carclazyte has; Effect with adsorpting pigment; Reduce the consumption of carclazyte in the grease-decolor process, reduced production cost, saved water washing process in the operating process.
The present invention realizes through following steps: one, the VT 18 behind the alkali refining is put into and taken off the soap whizzer and remove most of soap stock; Two, water content in oil content 0.2% ~ 0.6% after taking off the soap whizzer to take off soap adds 0.2% ~ 0.8% useless carclazyte, and mixes in oil; Low whipping speed 70r/min ~ 110r/min; Under 80 ℃ ~ 130 ℃ of the adsorption temps, soap 20min ~ 70min is taken off in absorption, thereby removes residual soap; Three, material is carried out spinning, gained is treats bleached oil.
Embodiment:
Below in conjunction with embodiment, the present invention is further described.
Embodiment one: one, the VT 18 behind the alkali refining put into take off the soap whizzer and remove most of soap stock; Two, water content in oil content 0.2% ~ 0.6% after taking off the soap whizzer to take off soap in oil, add 0.2% ~ 0.8% useless carclazyte, and thorough mixing is even; Low whipping speed 70r/min ~ 110r/min; Under 80 ℃ ~ 130 ℃ of the adsorption temps, soap 20min ~ 70min is taken off in absorption, thereby removes residual soap; Three, material is carried out spinning, gained is treats bleached oil.
