Abstract

A device for drying dairy and vegetable products, including an evaporation device, a drying chamber, a spraying element, filter elements, a device for secondary drying, means for supplying a drying agent, characterized in that it further comprises electrodes for creating an electromagnetic field of extremely low frequency (ELF EMF) located in the drying chamber, a condenser for cooling the spent drying agent located after the drying chamber, and an evaporator for heating the spent drying agent, decomposition apparatus after the secondary drying.

Description

The utility model relates to the food industry, namely to devices for drying dairy and vegetable products.

A device for drying serum containing a chamber for concentration, a spraying part, pipelines for supplying and discharging a drying agent, a device for crystallization and a device for final drying is known (US Pat. No. 5,006,204).

The disadvantage of this device is the insufficiently high quality of drying.

The prototype of the utility model is a device for drying a liquid with a high content of carbohydrates (patent RU 2377779 dated 01/10/2010), to obtain a non-sticky powder, including an evaporation device, a crystallizer, a drying chamber, in the upper part of which there is a spraying element, a filtering element, a device for post-crystallization, a device for secondary drying, means for supplying a drying agent, means for removing spent drying agent through a filter element.

The disadvantages of this device are the high energy consumption, high temperature drying, affecting the quality of the finished product.

The objective of the utility model is to develop a device for drying dairy and vegetable products, as well as expanding the arsenal of products for this purpose.

The technical result is to improve the quality of finished products, accelerate the drying process, reduce energy costs.

The technical result is achieved in that the device for drying dairy and vegetable products includes an evaporation device, a drying chamber, a spraying element, filter elements, a device for secondary drying, means for supplying a drying agent, and further comprises electrodes for creating an electromagnetic field of extremely low frequency ( EMF ELF) located in the drying chamber, a condenser for cooling the spent drying agent located after the drying chamber, and an evaporator for heating spent go drying agent located after the device for secondary drying.

The impact of the ELF EMF will accelerate the drying process of dairy and vegetable products by releasing the molecules of bound moisture contained in the product and increasing the rate of its internal diffusion. In addition, the ELF EMF promotes the penetration of the temperature of the medium into the cell, as a result of which the drying process can be carried out at lower temperatures, which will positively affect the quality of the finished product.

A condenser located between the drying chamber and the post-crystallization device will allow the use of exhaust drying gas for the operation of the post-crystallization device.

The evaporator for heating the exhaust drying gas, located after the device for post-crystallization, will allow the use of exhaust drying gas for the second drying process.

The figure shows a device for drying dairy and vegetable products, containing an evaporation device (1), a drying chamber (2), with a spray element (3) located in it, filter elements (4), electrodes for creating an ELF EMF (5), means for supplying a drying agent (6), a condenser for cooling the spent drying agent (7), an evaporator for heating the spent drying agent (8), a device for secondary drying (9).

A device for drying dairy and vegetable products works as follows. The dairy and vegetable product enters the evaporation device (1) for concentration to a solids content of 30% to 40%. Then the product is sent to the drying chamber (2) together with the drying agent supplied from the means for supplying the drying agent (6), in which the product is sprayed through the spraying element (3), exposed to the ELF created by the electrodes (5) and dried to the content solids from 10% to 20%. Then the product enters the device for re-drying (9), where it is dried to a dry matter content of from 4% to 8%. The spent drying agent obtained after drying the product in the drying chamber (2) passes through the filter elements (4), enters the condenser (7) for cooling, from where it is sent to the device for re-drying (9). The spent drying agent from the device for re-drying (9) is sent to the evaporator (8) for heating and use in the next drying process.

Thus, the proposed utility model will reduce the energy consumption required for the drying process of dairy and vegetable products, as well as get the final product of high quality.
