RU2013068C1 - Method for separation of lumped frozen products - Google Patents

Abstract

FIELD: fruit-and-vegetable industry. SUBSTANCE: lumps of frozen products are separated by applying compressing pressure of 5 to 16 kg/cm² and shear pressure of 2,5 to 3,5 kg/cm² with the movable cheek vibrating at 180-240 vibrations per minute and at an amplitude of 2 to 20 mm. EFFECT: higher efficiency. 3 cl

Description

 The invention relates to the fruit and vegetable industry and can be used on refrigerators of the canning industry enterprises and on commercial distribution refrigerators for breaking lumps of frozen frozen products.

 There are no methods for breaking up clods of frozen frozen foods, preserving the original form of each unit, both abroad and in the USSR.

 The use of existing methods does not ensure the goal, namely the safety of its original form. The use of grinding methods for other types of frozen products does not provide the goal, namely the safety of its original form. So, (in Pat. NDP Pat. No. 138635, Applicant WIZSZA Szkila Inzynierska), the frozen meat blocks are crushed using two drums rotating in the opposite direction with sharp spikes located on their surface.

 Due to the difference in diameters of the individual drum zones, the product is cut with the peripheral edges of the drum into strips equal in width to the width of the zones with different diameters.

 The product strips thus obtained are then cut into pieces of approximately the same size.

 This method does not ensure the preservation of the form of the product with a piece by piece separation, which is not permissible.

 The same applicant for patent PN 138634 uses a screw crusher to crush blocks of frozen products. However, this crusher does not meet the goal, as it does not ensure the preservation of the shape of the product.

 The company "IEDINSTVO" (SFRY) has developed a method for crushing frozen blocks using a cutter that cuts blocks into pieces of indefinite shape for subsequent processing of the product into juices and pastes for baby food.

 This crusher does not meet the intended purpose, as it does not preserve the original form inherent in fresh fruits and vegetables.

 In the USSR, crushers are used to crush frozen garlic, working according to the principle of impact by moving parts, for example, using a hammer crusher designed for the production of powdered sugar and granulated sugar.

 This method does not provide the goal, as it does not preserve the original shape of the fruit.

 The goal is achieved by the fact that in the known method of separating lumps of frozen frozen product, including breaking lumps of frozen product between the stationary and swinging movable cheeks, the operation of separating product units is carried out with a single issue between the ribbed roll and the lower part of the stationary cheek.

The second difference is that the units of the frozen product are separated at a compression pressure of 5 to 16 kg / cm ² and a shear pressure of 2.5 to 3.5 kg / cm ² .

 The third difference is that the units of the frozen product are separated at an oscillation frequency per minute of the moving cheek from 180 to 240 and an amplitude from 2 to 20 mm.

 This method allows you to separate units frozen in lumps of frozen product by the piece, maintaining the original shape of each unit of the product without damaging it.

PRI me R. Lumps of frozen frozen product enter the space between the stationary and swinging movable cheeks of the crusher, and then the product falls into the gap between the ribbed roll and the lower part of the stationary cheek, where at a pressure of 5 to 16 kg / cm ² and a shear pressure of 2.5 to 3.5 kg / cm ² , as well as the oscillation frequency of the movable cheek from 180 to 240 per minute and an amplitude of 2 to 20 mm, product units are separated with their single issue with the preservation of their original shape.

 Technical and economic efficiency lies in the fact that, due to the different periods of growth of fruits and vegetables, they are frozen during the processing season and stored in various containers for a sufficiently long period in refrigerators. Then, during the off-season period, vegetable and fruit-berry mixtures are prepared from pre-frozen components. When storing frozen foods, they freeze.

 Freezing of the product leads to a deterioration in its quality, loss of presentation, does not allow the formation of a mixture, disrupts the filling apparatus, reduces the productivity of the lines.

 Breaking lumps of frozen foods eliminates these shortcomings. In this case, a prerequisite is the preservation in the process of breaking lumps of the original form of the frozen product.

 However, a method that ensures the preservation of the form of the product when breaking frozen clods, both abroad and in our country, does not exist. This operation is performed manually using a hammer, sledgehammer.

 Using the proposed method for breaking clods of frozen frozen product ensures the release of quick-frozen mixtures in the off-season, the commercial quality of the products, the elimination of manual labor, the mechanization of the process, the stability of filling and packaging machines, the increase in productivity of production lines of quick-frozen products.
