(57) Abstract:

The inventive device for processing grain propionic acid contains vertical contact chamber with means of load distribution and unloading of grain in a continuous stream and at least one spray propionic acid, placed in the bottom of the camera and made in the form connected to the source of the ultrasound beam hub longitudinal vibrations with a convex front surface and covering it with a gap of a hollow sleeve for submission to the cavity acid. The spray also contains electret diffuser behind the front surface of the hub, electret is made and the means of distribution of grain, and the electrets of the cone and means of distribution heteropolar. 2 Il.

The invention relates to equipment for preservation of grain propionic acid in combination with electroaparataj and ultrasonic irradiation.

A device for processing grain propionic acid containing vertical contact chamber with means of load distribution and unloading of grain in a continuous stream and one spray propionic acid, placed in the lower part of the th grain rice propionic acid.

The disadvantages of this device are high flow propionic acid and low reliability sterilization of grain.

Also known device for processing grain propionic acid containing vertical contact chamber with means of load distribution and unloading of grain in a continuous stream and two spray propionic acid, placed in the lower part of the chamber is symmetrical to its axis and in the form of nozzles (Buriak E. C. Biochemical rationale and development of a chemical method of canning rice-grain optimum technological humidity. Abstract. dis. on saisc. exercises. degree K. the so-called Krasnodar, KPI, 1987, S. 5-6).

This device has several smaller consumption of propionic acid at the expense of a somewhat more uniform distribution in the mass of grain.

The objective of the invention is to reduce the consumption of propionic acid and reliability of sterilization of grain.

The problem is solved in that the device for processing grain propionic acid containing vertical contact chamber with means of load distribution and grain unloading the market, according to the invention is made in the form connected to the source of the ultrasound beam hub longitudinal vibrations with a convex end surface, covering it with a gap of a hollow sleeve with a feed channel propionic acid and electret diffuser placed over the end surface of the hub, and means of distribution of grain made of electret material, while the electrets of the cone and means of distribution of grain made heteropolar.

This allows to reduce the consumption of propionic acid by improving the uniformity of its distribution within the grain mass and improve the reliability of sterilization of grain by increasing the probability of destruction cyclotorsion forms of flora.

In Fig. 1 shows a diagram of the device of Fig. 2 - spray propionic acid.

A device for processing grain propionic acid contains vertical contact chamber 1, tool 2 download tool 3 distribution made of electret material, the tool 4 unloading grain running in a continuous stream, and at least one (in the drawing two) spray 5 propionic acid. The latter contains the source 6 ultrazyme the hub 7 with a clearance of 9 hollow sleeve 10 with a channel 11 filing propionic acid and electret diffuser 12, posted by the surface 8. The electrets means 3 and the diffuser 12 is heteropolar.

The device operates as follows.

Grain means 2 is fed into the chamber 1 to 3, in contact with which the grain flow is distributed evenly over the cross section of the chamber 1, and each weevil acquires a static electric charge. At the same time in the camera 1 counterflow grain nozzles 5 serves dispersed flow propionic acid. To do this, the channel 11 in the sleeve 10 into the gap 9 on the side surface is movable from a source 6 of the ultrasound beam hub 7 of the longitudinal oscillations serves propionic acid in jet mode. Under the effect of dilution arising from the end surface 8 of the hub 7 propionic acid moves through the gap 9, reaches the surface 8 and sprayed it wide torch due to its convexity. Torch dispersed propionic acid passes through the diffuser 12, acquires a static electrical charge of opposite potential, and enters the chamber 1. In the interaction between flows of grain and propionic acid under the action of electrostatic forces of attraction of opposite charges potential drops propionic acid etc which I have to complete disappearance, which leads to the regulation of the distribution of propionic acid in the grain mass. Simultaneously dispersed flow propionic acid transmits grain energy of ultrasonic oscillations. As a result of surface microflora of each weevil is subjected to the combined effect of chemical, electrostatic and ultrasonic treatment. Their combination leads to a greater probability of destruction kislorodozaschitny microflora, i.e. increases the reliability of the sterilization of grain. The thus treated grain from the camera 1 is removed by the tool 4 and is supplied to the storage.

Thus, the proposed device allows to reduce the consumption of prescribed acid and to improve the reliability of sterilized grain.

A device for processing grain propionic acid containing vertical contact chamber with means of load distribution and unloading of grain in a continuous stream and at least one spray propionic acid, placed in the lower part of the chamber, characterized in that the spray propionic acid made in the form connected to the source of the ultrasound beam hub longitudinal vibrations with a convex face on top of the a, placed behind the front surface of the hub, and means of distribution of grain made of electret material, while the electrets of the cone and means of distribution of grain made heteropolar.

SUBSTANCE: invention relates to the food industry. The device comprises a hollow thermally insulated housing with an annular insert placed in it, mounted with a gap relative to the wall, the lid and the bottom of the heat-insulated housing. In the heat-insulated housing a circulation loop is formed, filled with liquid coolant, comprising a central duct with an electric heater located in it, and an annular peripheral channel with a tubular heat exchanger located in it for passage of the processed food product, mounted in the annular peripheral channel on the countercurrent circuit. The annular peripheral channel is provided with at least one spiral chute mounted on at least one side of the tubular spiral heat exchanger equidistant to it.

EFFECT: invention enables to intensify the heat exchange process, to reduce the time of heat treatment of the product, to create a part-load mode of heat treatment, which reduces the risk of "burning".
