Peanut is a high oil content of oil,its oil content has reached about 50%.A good peanut protein equipment and full peanut raw material are the main factors affecting peanut oil yield.So how to improve the peanut oil rate?
(1)the choice of peanut raw materials,"multiple births"peanut a shell with 3 to 5 peanuts peanut oil rate is relatively high,but this kind of peanut growth environment is very demanding,so it is difficult to buy in the market.The quality of peanut raw material directly determines the quality of oil and oil yield,the selection of peanuts must choose full and regular grain size as far as possible,to ensure the water content of raw materials(general water content between five to ten percent),before frying to remove impurities with food sieve machine.
(2)operators to operate the screw press has rich practical experience,to avoid manual operation is not skilled and lead to the problem of affecting output,oil pressing process to master,what time into the oil,fry the fire master,all must have precision control.The loss of mechanical equipment is not conducive to improving the oil production,usually pay attention to good maintenance,to check the wearing parts regularly,if the parts wear must be replaced in time.
(3)equipment health problems,before pressing oil to check whether there is a foreign body oil line,the cake is too thin,if too thin will increase the wear of the press screw,reduce the service life of the press screw.
The problem of pressing time,the accumulation of experience for a long time,the longer the continuous oil pressing time,the more smooth the oil,so we should try to concentrate the oil pressing,can be replaced by many people for 24 hours non-stop pressing,but must pay attention to the control of temperature,so as not to peanut oil press temperature is too high failure.In order to prevent heat loss,some heat preservation measures should be taken during the pressing process,so as to ensure the stability of oil yield.
(4)oil cake problem,when pressing oil to control the cake thickness,prevent the cake is too thick.
The plasticity of pressing material is increased by heating,but decreased by cooling.The temperature of pressing material not only affects the plasticity and the effect of oil production,but also affects the quality of oil and cake.In addition,with the increase of the water content of the pressing material,its plasticity also gradually increases,when the water reaches a certain point,the squeeze oil is the best,then the water content is called"better water"or critical water,for a certain kind of pressing material,under certain conditions,there is a better water range for pressing oil.
(5)selection and quality of peanut protein equipment
Peanut oil processing equipment is used to obtain peanut oil from peanut equipment.So peanut oil yield and peanut oil processing equipment is inseparable.Therefore,the inferior quality of oil refining equipment will directly affect the production process of peanut oil,and also cause the problem of how much peanut oil is produced and whether the oil is smoothly produced.Henan subcritical peanut protein equipment uses low temperature to produce peanut oil and peanut protein.The process is as follows:
(1)Peanut pre-pressing:
After taking off the red coat,the peanut kernel can be made into oil at low temperature,which can not only get the most distinct fragrant peanut oil in line with consumer psychology,but also form the cake suitable for extraction.
(2)Low-temperature extraction:
Low denaturation peanut meal with residual oil≤1.5%was obtained.
(3)Production of peanut protein powder:
After peanut protein powder special grinder,sterilization.Peanut protein powder protein dry base>50%,the total number of colonies does not exceed 30,000 cfu/g.
