Apparatus for supplying grain and flour to container of food processing machine

A grain and flour supply apparatus for supplying grain and flour to a container of a food processing machine, comprising:

• a holding bin provided above the container and comprising an exhaust port from which gas is discharged, an introduction port into which the grain and flour are introduced, and a supply port which supplies the grain and flour to the container;
• a first vacuum breaker valve opening and closing the exhaust port;
• a second vacuum breaker valve opening and closing the introduction port;
• a third vacuum breaker valve opening and closing the supply port;
• a temperature sensor measuring a temperature in the holding bin and outputting a measured temperature;
• a vacuum device comprising one or more vacuum pumps connected to the exhaust port via the first vacuum breaker valve, and drawing a vacuum in the holding bin;
• and
• a control device configured to control the first vacuum breaker valve, the second vacuum breaker valve, the third vacuum breaker valve, and the vacuum device, and set with a target temperature,
• wherein the control device operates the vacuum device in a state where the first vacuum breaker valve is opened and the second vacuum breaker valve and the third vacuum breaker valve are closed until a pressure in the holding bin is lowered to a pressure, at which a temperature of the grain and flour starts to decrease due to vaporization latent heat, or less and the measured temperature in the holding bin falls to the target temperature or less.
