Embodiment 1

[0012] A high-efficiency treatment process for brown board, the process is as follows:

[0013] (1) After sending the brown board into the cooking tank, inject water into the cooking tank through the water inlet on the tank body until the water is submerged to two-thirds of the stacking height of the brown board in the tank;

[0014] (2) Inject steam into the cooking tank through the steam heating system to heat up to a temperature of 120°C, and at the same time apply pressure to the tank until the pressure in the tank reaches 4 kg, that is, 4 barg, and cook under pressure for 2 hours, then cook under pressure 2 hours;

[0015] (3) After the pressure-holding cooking is completed, the cooking tank is relieved. After the pressure is relieved, the water in the tank is released from the drain, and then the discharge port of the cooking tank is opened, and the cooked brown board is sent out from the discharge port. ;

[0016] (4) Send the cooked brown board to the silk grabbing e...

Embodiment 2

[0018] A high-efficiency treatment process for brown board, the process is as follows:

[0019] (1) After sending the brown board into the cooking tank, inject water into the cooking tank through the water inlet on the tank body, until the water submerges more than two-thirds of the stacking height of the brown board in the tank;

[0020] (2) Inject steam into the cooking tank through the steam heating system to heat up to a temperature of 150°C, and at the same time apply pressure to the tank until the pressure in the tank reaches 3 kg, and cook under pressure for 1.5 hours, then cook under pressure for 2.5 hours;

[0021] (3) After the pressure-holding cooking is completed, the pressure of the cooking tank is released. After the pressure is relieved, the water in the tank is released from the drain, and then the outlet of the cooking tank is opened. After the material in the tank is properly cooled, the cooked The brown board is sent out from the discharge port;

Embodiment 3

[0024] A high-efficiency treatment process for brown board, the process is as follows:

[0025] (1) After sending the brown board into the cooking tank, inject water into the cooking tank through the water inlet on the tank body until the water is submerged to two-thirds of the stacking height of the brown board in the tank;

[0026] (2) Inject steam into the cooking tank through the steam heating system to heat up to a temperature of 130°C, and at the same time apply pressure to the tank until the pressure in the tank reaches 4 kg, and cook under pressure for 2.5 hours, then cook under pressure for 2 hours;

[0027] (3) After the pressure-holding cooking is completed, the cooking tank is relieved. After the pressure is relieved, the water in the tank is released from the drain, and then the discharge port of the cooking tank is opened, and the cooked brown board is sent out from the discharge port. ;

Abstract

Disclosed is an efficient palm plate processing technology. Palm plates are fed into a cooking pot. Water is added into the cooking pot till two thirds or more of the stacking height of the palm plates inside the pot are soaked with the water. Then, steam is injected into the cooking pot for heating, heating is performed so that the temperature of 120-150 DEG C can be reached, pressure is applied till the pressure inside the pot reaches 3-4 kg, and pressure maintaining cooking is performed for 1.5-2.5 h after pressure application cooking is performed for 1.5-2.5 h. Then, pressure relief of the cooking pot is performed, water inside the pot is drained after the pressure relief is finished, and the cooked palm plates are discharged. Finally, the cooked palm plates are grabbed and dried in the sun to obtain palm fiber threads, and the whole palm plate processing technology is finished. The technology is short in processing time and low in heat energy consumption, saves labor, is efficient in production and does not pollute the environment.

Description

technical field [0001] The invention belongs to the technical field of palm processing. Background technique [0002] The palm leaf refers to the petiole part of the palm. For a long time, folks have been cooking brown board to obtain brown silk. With the advancement of technology and the increase of social demand, the demand for brown silk in the market is increasing, and the way of processing brown board to obtain brown silk has gradually expanded from family workshops to industrial processing methods with a certain scale. But no matter which processing method is adopted, the existing processing method is to boil the fresh or dried brown board in an open large pot for at least 60 hours, usually three days and three nights, and then boil it. Take out the brown board, squeeze the water and draw it. This processing method is time-consuming, laborious, troublesome to operate, extremely low in processing efficiency, wastes fuel, has low efficiency of heat energy utilization,...
