Description
Technical field
The invention belongs to oil plant preprocessing technical field, be specifically related to a kind of fresh rice bran pretreatment technology and corollary apparatus thereof.
Background technology
Containing multiple enzyme, especially lipase and lipoxidase in rice bran, easily cause the acid value of fresh rice bran and hair Rice pollard oil to raise rapidly in the short period of time, grease even can be made to decompose completely in 2 ~ 3 days.Therefore, usually need grease to extract from fresh rice bran as early as possible in actual production, or (in 10 ~ 20 minutes) carry out stabilization treatment to rice bran in time, make the enzymatic inactivation contained by it.
In addition, the rice crushed rices usually containing 1% ~ 4% in the fresh rice bran of rice factory output.The main component of rice crushed rices is starch, very easily absorbs moisture and expands, and then causing material adhesion, can produce have a strong impact on the perviousness of material and blanking.On the other hand, rice crushed rices also easily absorbs oil content, affects the normal extraction of grease.Therefore, in time rice crushed rices is separated from fresh rice bran the recycling being both conducive to meter crushed rices, be conducive to again the storage of rice bran and the extraction of Rice pollard oil.
Summary of the invention
The object of the invention is to provide a kind of pretreatment technology for fresh rice bran, meanwhile, provide fresh rice bran pretreatment unit supporting to be with it then another object of the present invention.
Based on above-mentioned purpose, this invention takes following technical scheme:
A kind of fresh rice bran pretreatment technology, comprises the following steps: 1) carry out pre-treatment (separation of chaff crushed rices) to fresh rice bran, obtain meter crushed rices content lower than 1% purification rice bran; 2) collect purification rice bran, and sterilization deactivation and forming processes are carried out to it.
Collect isolated in step 1) cracking rice and rice crushed rices, so that do further recycling.
The corollary apparatus of described fresh rice bran pretreatment technology, comprise rice bran-brewer separator, collect Asta-3746 and sterilization forming machine, the blast inlet of rice bran-brewer separator is communicated with hot blast conveying pipe road, the described the other end in hot blast conveying pipe road is connected with the air outlet of airheater, and the hot blast conveying pipe road between airheater and rice bran-brewer separator is provided with fresh rice bran entrance; The upper air outlet of rice bran-brewer separator is connected with the blast inlet collecting Asta-3746 by pipeline; The discharge port collecting Asta-3746 is connected with the opening for feed of sterilization forming machine by feeding auger.
Described collection Asta-3746 comprises cyclone cylinder and is located at the aggregate bin of cyclone cylinder bottom, and aggregate bin bottom is provided with air sealer and discharge pipe successively, and the lower outlet of discharge pipe is the discharge port collecting Asta-3746.
Described cyclone cylinder top is provided with exhaust outlet, and this exhaust outlet is connected to the blast inlet of airheater by blower fan and warm air recovery channel.
Be provided with bottom described rice bran-brewer separator and crack rice and the outlet of rice crushed rices, crack rice and be provided with below the outlet of rice crushed rices and crack rice and rice crushed rices collection auger.
Trimmer conveyor is provided with near the discharge port of described sterilization forming machine.
The rice bran utilizing pretreatment technology provided by the invention to obtain is stablized, and is beneficial to transport and deposits; The acid value leaching hair Rice pollard oil maintains lower level, deposits acid value rise slowly.
Pretreatment unit supporting with it utilizes warm air that fresh rice bran is sent into rice bran-brewer separator, what sub-argument went out crack rice and rice crushed rices can be recycled further, isolated purification rice bran enters successively collects Asta-3746 and sterilization Machine, realize instantaneous sterilizing at the high pressure-temperature high humidity of sterilization forming machine and make enzyme deactivation, effectively can extend the staging life of rice bran.The material of releasing from sterilization forming machine can utilize trimmer conveyor send to storage or be directly delivered to leaching section.Utilize hot blast to carry rice bran can play pre-heat effect simultaneously, the heating-up time of rice bran in sterilization forming machine can be saved, promote sterilizing active rate and effect.
At room temperature be suitable for depositing more than one month by the rice bran that this device is pretreated; The acid value leaching hair Rice pollard oil maintains lower level, deposits acid value rise slowly.Meanwhile, this pretreatment unit also has compact construction, multiple functional, heat utilization rate high-technology advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
