Description

Automatic rice split charging device

Technical Field

Background

In recent years, with the continuous development and expansion of central kitchen enterprises, rice dispensers are also becoming one of the essential constituent devices in this field. The rice split charging machine is specially made for a central kitchen enterprise, and is a special device for charging cooked rice into a specially made container selected by the central kitchen enterprise according to a certain shape and gram weight. According to the temperature of the cooked rice during split charging, the split charging of a hot chain and the split charging of a cold chain are carried out, the split charging of the cold chain is carried out on the cooked rice or the post-cooked rice, the post-cooked rice is obtained by only enabling the cooked rice to be 7 and 8 ripens in the curing process, and the cooked rice with the same characteristic as the instant cooked rice can be obtained after heating the cooked rice at the set time and temperature according to prompts before the cooked rice is eaten by consumers after being processed by a specific process.

In view of the fact that gelatinized starch is eluted when the temperature of rice is reduced below 20 ℃, the viscosity is increased, resistant starch is generated, and the viscosity reduction degree is greatly increased along with the temperature, untreated pure rice is difficult to process into small units due to the high viscosity, namely, the untreated pure rice is separated by special means and is formed into blocks once meeting, so that a cooked rice cold chain split charging production line does not exist so far, and the research on the cooked rice cold chain production line is of great significance. At present, when cold chain split charging is carried out on the market, rice is quickly air-dried, or is mixed with grease, egg liquid and the like, so that the adhesiveness among rice grains is completely lost, and in such a case, the gram weight and the precision of the rice during split charging can be easily controlled. However, the addition of the additive to the cooked rice reduces the mouthfeel of the cooked rice.
