Embodiment 1

[0036] In Example 1, the rice bran stabilization treatment steps are as follows:

[0037] (1) Remove impurities from fresh rice bran through a 50-mesh sieve, weigh 2kg of rice bran, place it in a glass container, and flatten it to a thickness of 1.5cm; a 50-mesh sieve can remove most impurities, such as rice husk, broken Rice, etc., glass is a thermally stable material, and can ensure the passability of radio frequency, and flattening can also make the processing process more uniform.

[0038] (2) Place the glass container containing rice bran between the two polar plates of the radio frequency heating equipment, fix the distance between the upper and lower plates to 15cm, and set the radio frequency temperature to 120°C through the equipment control panel; the distance and the radio frequency temperature are obtained through experiments The better parameters obtained ensure the effect of protease inactivation, but correspondingly reduce the oil yield.

[0039] (4) Start the ...

Embodiment 2

[0041] In Example 2, the rice bran stabilization treatment steps are as follows:

[0042] (1) Remove impurities from fresh rice bran through a 50-mesh sieve, weigh 1.5kg of rice bran, place it in a plastic container, and flatten it so that the thickness is 1cm; the 50-mesh sieve can remove most impurities, such as rice husk, broken Rice, etc., plastics have good stability below 180 ° C, and are light in weight, which can ensure the passability of radio frequency, and flattening also makes the processing process more uniform.

[0043] (2) Place the plastic container containing rice bran between the two polar plates of the radio frequency heating equipment, fix the distance between the upper and lower plates to 20cm, and set the radio frequency temperature to 90°C through the equipment control panel; the distance and the radio frequency temperature are obtained through experiments Another preferred parameter obtained is that the protease removal effect is worse than that of Exam...

Embodiment 3

[0046]In Example 3, the radio frequency heating equipment used for rice bran stabilization treatment includes a support platform 1, a conveyor belt 2, a radio frequency unit 3, a hot air distributor 5, a hot air pipeline 6, a hot air generator 7, etc., and the conveyor belt 2 is installed On the support platform 1 , the hot air distributor 5 is placed in the radio frequency unit 3 , and the hot air distributor 5 is connected with the hot air generating device 7 through the hot air pipe 6 . The above structure forms three major systems, namely the conveying system, the radio frequency processing system, and the hot air processing system. These systems are simple in composition and easy to manufacture and install. The radio frequency unit 2 is composed of relatively arranged upper and lower plates 32 / 33, telescopic rods 31, upper frame 4, etc., the upper plate 32 is connected to the upper frame 4 through the telescopic rod 31, and the lower plate 33 is set It is connected with t...

Abstract

The invention discloses a rice bran stabilization method and a radiofrequency heating device. The treatment method comprises the following steps: removing impurities from fresh rice bran, weighing a certain amount of the rice bran, placing the rice bran in a container, spreading the rice bran to make the thickness be 1-1.5 cm, placing the container filled with the rice bran between two pole plates of the radiofrequency heating device, setting a spacing between the two pole plates at 15-25 cm and the radiofrequency temperature at 80-120 DEG C, carrying out radiofrequency treatment to quickly heat the rice bran to a required temperature, immediately taking out the heated rice bran, carrying out heat insulation for 5-30 min by using an oven with the temperature being the required temperature, taking out the rice bran, naturally cooling the heated rice bran, filling a sealing plastic bag with the cooled rice bran, and storing the rice bran at 30 DEG C. The radiofrequency heating device comprises a supporting table, a conveyor belt, a radiofrequency unit, a hot air distributer, a hot air pipeline and a hot air generator. The rice bran stabilization method and the radiofrequency heating device reach the rice bran stabilization purpose through sending the rice bran to the conveyor belt of a radiofrequency heating system and allowing the rice bran to move with the conveyor belt and be irradiated with radiofrequency in order to kill the enzymes contained in the rice bran.

Description

technical field [0001] The invention belongs to the field of rice bran stabilized production, and in particular relates to a rice bran stabilized treatment method and radio frequency heating equipment. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Rice is one of the most important food crops in the world. my country is the largest rice producer in the world, and the output of rice accounts for about 37% of the world's total output. Rice bran is the part of the epidermis that is removed during the process of processing brown rice and grinding off the epidermis and germ to become palatable white rice. As the main by-product of rice processing, rice bran can produce about 10 million tons per year. It is also a kind of resource with great development potential and high added value. Modern research proves that r...
