Abstract

The invention relates to the food industry, in particular to the production of malt, and can be used in its brewing and alcohol industries when producing malt in malt freezing pneumatic tools with augers. The purpose of the invention is to improve the quality of malt and reduce the loss of dry matter. relative humidity of the aerating air leaving the malt layer and comparing the obtained values with their given values, and in case of deviation of these parameters from These values provide additional mixing, cooling and moistening of malt 1 sludge.

Description

The invention relates to the food industry, in particular to the production of malt, and can be used in its brewing and alcohol industries when producing malt in malt freezing pneumatic boxes with augers.

The purpose of the invention is to improve the quality of malt and reduce the loss of dry matter.

The drawing is a diagram explaining a method for automatically controlling the malting process.

The scheme contains maltiser 1, running motor 2. drive 3 augers malnutrider 1, exhaust fan 4, exhaust device 5. humidity sensor 6, temperature sensor 7 humidity comparison unit 8, temperature comparison unit 9, operation mode selection unit 10 actuator 11 for water supply and liquid dispensers 12

When the malt sweeper 1 is started up, the running engine 2 is turned on automatically. Drive 3 of the screw and exhaust fan 4. After aerating the malt layer, the aerating air enters the exhaust device 5, at the outlet of which the humidity sensor 6 and temperature sensor 7 are located, control parameters of exhaust air. The signals from the senders 6 and 7 arrive at blocks 8, 9 comparing the humidity and temperature, respectively. In case the exhaust air temperature exceeds the set one, a signal is generated at the output of the comparison unit 9, which, through the mode selection unit 10, turns off the propulsion motor 2 of the malt dryer 1. At the same time, the malt puller 1 stops and intensive aeration of the found hot spot occurs with the screws running until the temperature of the exhaust air becomes equal to the set point.

At the same time, at the output of the comparison unit 9, a signal is generated to start the running engine 2, which through the operating mode selection unit 10 will turn on the running engine 2 of the malt sweeper 1 carriage, which will lead to its movement.

In the event that the humidity of the exhaust air becomes lower than the set value, the signal from the output of the comparison unit 8 through the operation mode selection unit 10 is supplied to the actuator 11, which opens the supply of humidifying water to the sprayers 12. The malt layer from the malting malt 1 is additionally moistened until the carriage reaches the crate area above which the air humidity is higher than the set one.

A signal about this from the humidity sensor 6 is supplied to the comparison unit 8, the output signal from which is reversed and through the operating mode selection unit 10 and the actuator 11 stops the supply of moistening water to the nozzles 12.

In the case when the sensors b and 7 of humidity and temperature detect a deviation of temperature and humidity from the set values, the output signals from blocks 8 and 9, comparing through block 10, the mode of operation will stop the operation of the drive engine 2, which will lead to increased turning and irrigation found hearth. When the temperature of the exhaust air reaches a predetermined value, the signal from the output of the comparison unit 9 will start the running engine 2, which will lead to the continuation of movement of the carriage of the malt malt 1, and when the humidity of the exhaust air reaches the specified value, the signal from the output of the comparison unit 8 will stop the water supply to the sprayers 12, closing the actuator 11.

Operation mode selection unit 10 allows both joint and separate temperature and humidity control to be performed. When the maltiser 1 occupies one of the extreme positions, the power to the circuit is removed and a new cycle of operation is performed after the malt maltser 1 is started up at the next pass through the box. Invention Formula A method for automatically controlling the malting process, which involves measuring the temperature of a layer of malt from a moving malt grower. comparing it with a target value and performing additional mixing and cooling of the malt when the current temperature is exceeded at a fixed position of the malt fermer, characterized in that, in order to increase quality of malt and reduction of dry matter losses, additionally measure the value of the relative humidity of the aerating air at the outlet of the layer and compare it with a predetermined value; in addition, when the air temperature rises above the predetermined and the relative humidity does not exceed the predetermined value, the malt is stirred when the carriage is stopped malt spreader, and if relative humidity below the setpoint and the temperature in the specified range irrigate the malt layer with water without stopping the malt carriage, and when the relative humidity decreases relative to the set value and the temperature rises, additional mixing and irrigation are carried out when the malt curler carriage is stopped and the drive is automatically started last and termination of irrigation when the values of temperature and relative humidity reach the set values.
