Characteristics of vacuum paste making machine

Vacuum paste machine is widely used in toothpaste, cosmetics, food, chemical and other industries viscous paste manufacturing. The whole set of equipment is equipped with paste making machine, premix pot, glue pot, powder hopper, colloid pump and operation platform.

Vacuum paste machine is characterized:

(1) The paste is made in a closed container and operated in a vacuum state.

(2) Equipped with paddle stirring and scraper, so that the material does not produce accumulation and dead angle.

(3) Equipped with a high-speed homogenizer or colloid mill to make the material uniform and delicate.

(4) One-step process can be used to complete all paste-making operations in the paste-making machine, effectively reducing material loss.

(5) Supporting raw material conveying system, automatic metering and control system, through computer operation, to achieve paste automation.

Structural features of vacuum system:

(1) The cylinder is made of three layers, both inside and outside are made of stainless steel, with positive pressure resistance of 0.2MPa and negative pressure resistance of -0.1MPa. The jacket is used for heating or cooling, with positive pressure resistance of 0.3Mpa.

(2) The scraper stirring is a large wall-sticking scraper and a central scraper rotating in the forward and reverse directions, and the rotating speeds are 6RPM and 12RPM respectively. When stirring, the materials can be scraped off the cylinder wall, the temperature transmission is uniform and sufficient, and the effect of turning up and down is formed.

(3) The high-speed homogenizer is placed at the bottom of the paste making pot with a rotating speed of 1450RPM and a gap of 1-2mm between the inner and outer rotors. After the powder is sucked from the bottom, it is sprayed to the top through the homogenizer, thus achieving the effect of making the paste delicate.

(4) The vacuum pump adopts a water-sealed two-stage vacuum pump, and a buffer tank is equipped between it and the paste making pot to isolate the materials accidentally brought out.

(5) The hydraulic lifting mechanism is a double-column double-hydraulic differential, which is convenient for the maintenance of the fittings in the pot and the inspection of the paste in the pot.

(6) Circulating water is used for jacket cooling, the water pressure is controlled below 0.3Mpa, and the temperature is set by the control system.

(7) The discharge port is located at the bottom of the paste making pot, and a colloid pump with a flow rate greater than 100L/min is used for discharge.
