The device relates to a technique for extracting the juice from berries and fruits by heating raw materials without mechanical deformation and can be used at home and at public catering enterprises where there is a microwave in microwave ovens.

Known Soko-soon-sterilizer for extracting the juice from fruits and vegetables, including hermetically sealed metal container, the lower part of which water and above water is perforated container for fruits, flat tank for collecting juice equal to the diameter of the containers for fruit, and a glass jar for pumping in her collected juice is running and innovator. 1991, No. 7, S. 15). Disadvantages Soko-soon-sterilizer is that the process of extracting the juice it takes place during heating of raw materials in the vessel to 104oC from an external source of heat (electric or gas stoves). In this heating mode, the product is under excessive pressure of water vapor at 0.2 kg/see High temperatures in the steaming mode destroys some vitamins and enzymes, which reduces the quality of the juice that is diluted with water by condensation of steam. In addition, the design of the device itself is quite bulky, requires additional time for Assembly, depressurization and disassembly of the apparatus, and also a large amount of energy for heating design and heat flooded into the device water to a boil and creation of excess capacity steam pressure.

There is a method of accelerated cooking of vegetables, fruits and berries in microwave microwave ovens by internal heating of the product under the action of electromagnetic field frequency of 2450 MHz. The heating process is carried out in a matter of minutes without heating environment with a minimum expenditure of energy during simultaneous sterilization of the resulting product. The preparation is carried out in the volume lay product, to prevent splashing of product from the vessel during heating (cooking) (Nekrutman S. C. ultra-fast cooking or microwave in your house. M Agropromizdat, 1988, S. 98).

The juice released during heating of fruit and berries in a microwave oven, can subsequently be drained from the vessel and be used as a standalone product, however, this is an advanced operation and juice are not separated completely, as is the secondary mixing with the remnants of the original product when it overflows. To obtain the juice in microwave ovens, it is desirable to develop a special device that provides the maximum allocation of juice from raw material and collecting it in a separate bowl. The objective of the invention is to expand the possibilities of using domestic microwave microwave ovens for processing of agricultural products by creating a device that allows on a new technical level to obtain high-quality sterile juice from berries and fruits in the processing of their microwave radiation. The juice should in the process of getting it to gather in the vessel (Bank), in which it can be stored in the next time. The device should be simple in manufacture and operation, with the possibility of using sporochnales of the invention is implemented using a device, it is shown in Fig.1.

In Fig. 1 schematically shows a General view of the device in section.

The device is made in the form of consoles, consisting of the container 1 with the cover 2 and the intermediate Societatea funnel 3, installed on the vessel for collecting juice 4.

All component parts of the device: capacity 1, cover 2 and Societatea funnel 3 is made of radiotransparent material, in particular from food high-pressure polyethylene, Teflon or heat-resistant glass.

Capacity 1, serves to place the berries, from which is distilled juice, has an upper portion corresponding to the dimensions of the working chamber of the microwave oven (with a diameter of approximately 250-320 mm) and a perforated plate, preferably in the form of a truncated cone. The diameter of the perforation is made in the range of 2 to 5 mm, so that the holes did not sticks juice and didn't miss the small berries and seeds down. The height of the upper part of the vessel 1 is made of 30-50 mm, so that a layer of berries, placed in containers, uniformly processed microwave radiation with a frequency of 2450 MHz throughout the volume. Perforated bottom containers are manufactured in the form of a truncated cone with an angle greater than or equal to 90oto ensure runoff allocated juice and not create b is the better of the sides and top of the working chamber of the microwave oven from contact with spray juice, allocated from the berries during microwave processing. Societatea funnel 3 has a lower neck the size of a standard glass jars, which is used in the device as the vessel 4 to collect the juice. Societatea funnel 3 ensures the stability of the entire device when it is built. Upper neck Societatea funnel 3 corresponds to or larger than the area of the perforated bottom of the tank 1 and collects the juice released from the berries through a perforated plate. The area of the perforated surface of the bottom is larger than the area of the lower (drain) of the neck of the funnel. The angle of the walls Societatea funnel 3 must be equal to or less than the angle of the conical bottom of the tank 1, to provide a drip of juice in the vessel (jar) 4 by gravity.

The capacity of the vessel for collecting juice 4 (banks) are limited by height. The overall dimensions of the device for microwave ovens with the volume of the working chamber 32 l should not exceed 210 mm to Adjust the size of the device height is possible by the selection of the vessel (banks) to collect the juice.

Device for producing juice from the berries in a domestic microwave oven works as follows.

Berries (cranberries, the cranberries, the cranberries, currants, sea buckthorn, h cm capacity 1, close the lid 2 and put on sokoudjou funnel 3, is inserted into the vessel for collecting juice (jar) 4. The assembled device consisting of elements 1; 2; 3; 4, put into the working chamber of a household microwave oven, directly on her bottom. Glass stand from the oven when it is removed. The oven door is closed. Ask a processing program and include a microwave.

Under the action of microwave radiation can cause heating of the product and distillation of the juice. The juice flowing through the perforated bottom of the tank 1 falls in the intermediate sokoudjou funnel 3, and thence by gravity into the vessel (jar) 4.

After the specified time the microwave oven is turned off. The device is removed from the furnace. The prefix is removed from the vessel 4 and put aside aside. The juice is collected in the vessel (jar) 4, is directed for further use.

If the modes of operation of the furnace worked out and the vessel for collecting juice filled to the specified level, it is closed with a lid and roll, so as juice and Tara sterilized microwave radiation and do not require additional processing.

In the future, the juice obtained using the proposed device can be used to prepare juices, syrups, etc.

Berries, OS for pies or as a component of fruit tea, infusion or collection.

The duration and intensity of microwave processing of berries are selected empirically with regard to humidity, the quantities and types of berries, as well as from the required quantity of juice and the purpose of its further use.

Example. The product, viburnum berries, prepared for processing (selected, washed and obsushenny in air) weight 1000 g load in the proposed device (container with a perforated bottom in the form of a truncated cone mounted on ZOLOTOGO funnel inserted into a glass jar to collect the juice, with a capacity of 500 ml) and placed in the working chamber of household microwave ovens "Titan" (the volume of the working chamber 32 l, usable capacity in the working chamber 600 watts). Total time of microwave treatment 25 min, with 1 min mode Min warm-up" (100% power) and 24 min mode "Moderate heat" (75% power). The volume of the collected juice 500, the Temperature of the juice 65oC. the Remains of the berries after forcing juice dried and used as a component of tea.

With current levels of production units of the device is not difficult. The tank cover and Societatea funnel can be manufactured by injection molding or by stamping ECI) Assembly units can be separately used in other operations in the harvesting of agricultural products in the home.

The tank 1 may be used for washing fruits, vegetables and fruits or as a container to store them together with the cover 2.

Societatea funnel 3 can be used as a normal filling funnel with spill compotes and preserves in glass jars.

The proposed device for forcing the juice from the berries in a domestic microwave oven is a versatile, easy to manufacture and should benefit from increased demand from the owners of microwave ovens engaged in harvesting of agricultural products and want to provide for their families natural diet juices.
