Induction heating system for demolding food products

Abstract

The invention relates to an induction heating system for demolding food products. The system is based in that the heat energy needed to be supplied in order to demould a food product from a metallic mold (3), is provided by induction coils (9) mounted on a rigid support (4) belonging to a module (1), and several of these modules (1) being mounted on a common tubular support (2), being fixed through a ball-coupling to a ring (5) and a polymeric joint (6). The induction coil (9) on each module (1) is positioned close to the surface facing the cavity of the rigid body (4) of the module (1) wherein the mold (3) containing the food product to be demolded is positioned.

Description

technical field [0001] As stated in the title of the invention, the present invention relates to an induction heating system for demolding food products, which utilizes an induction coil as a heating device capable of transferring the energy required for demoulding to the corresponding mould, without Physical contact is established between these two elements. [0002] The purpose of the invention is to increase the output of a corresponding line of cold products that need to be demoulded for use. For example, the system is applied to industrial lines of molded ice cream or any other cold food product that has to be demoulded, where the use of the system itself is practicable. Background technique [0003] As is known, for the demolding of cold products in a production line, which may for example be an ice cream production line, heat supply means are included to effect the demoulding. [0004] At present, heating is performed using steam or hot water, so that the energy tha...

AI Technical Summary

Problems solved by technology

[0004] Currently, the heating is performed using steam or hot water, so that the energy that can be provided for demolding is limited, and as a result, the production volume is limited

[0005] In addition, the application of water vapor or heat flow cannot be performed uniformly over the entire outer surface of the mold, which leads to deformation of the product, resulting in a loss of product quality

[0006] Another disadvantage caused by the use of water vapor for demoulding is the closeness to the product freezing channel of the production line

For both using steam or hot water, steam is generated which is introduced into the freezing tunnel where ice is formed, which reduces the energy efficiency of the freezing tunnel and increases downtime for maintenance

[0007] Finally, applying hot water or steam means water droplets will form, with the risk of bacteria
