MULTILAYER BOTTOM OF THE RESERVOIR FOR THE HIGH-TEMPERATURE PROCESSING OF FOOD PRODUCTS AND METHOD OT ITS PRODUCTION Russian patent published in 2012 - IPC A47J37/10 B23K20/08 

FIELD: food industry.

SUBSTANCE: multilayer bottom of the reservoir is used in the production of the dishware for high-temperature processing of food products. The bottom consists of two fixedly connected layers made of different materials motonically increasing from the center to the periphery. The contact line is made in the wavelike amplitude and the ratio to the wave length. Besides the maximum wave amplitude doesn't exceed 0,1-0,3 of the thickness of the most thin layer. The method of multilayer bottom production includes the connection of different materials by explosive welding. The driver material is made in the form of asymmetric rotary shell segment which axis is set perpendicularly to the fixed plate. The crowned surface of the shell turns to the fixed plate. Then the materials are connected with the explosive material layer posed on the concave surface of the layer with further activation in the center. Curve radius is defined according to the set ratio: where K - curve radius of the shell, a - angle between the axis and shell normal, r - interval between the center of the fixed plate and its crossing point with the normal, 5 - shell thickness, X - wave length of the welding seam in the distance from the center of the plate, and II are quickness of an explosive and the shell in the crossing point with the normal.

EFFECT: to increase the fatigue limit of the reservoir for the high-temperature processing food products.
