Description

Sterilizer for Food or Drugs in Liquid or Semiliquid status by utiliging Microwave dielectric heating}

The present invention relates to a sterilization apparatus for sterilizing liquid and semi-liquid foods and pharmaceuticals by microwave dielectric heating, and more specifically, to install a microwave chamber equipped with a microwave generator in multiple directions adjacent to each other in a longitudinal direction. The cylindrical tube with low permittivity is installed in one row or in multiple rows in the longitudinal direction of the chamber to sterilize the object to be sterilized by irradiation of microwaves in the process of transferring the object to be sterilized along the tube in the longitudinal direction of the multiple microwave chamber. It relates to an apparatus for permitting this dielectric heating to sterilize.

Various sterilizers currently used are sterilized by heating the sterilized object with steam or by stirring it in a cauldron by stirring or irradiating with radiation and ultraviolet rays.

In addition, there is a microwave sterilization method, but the size is limited to small packaged products, such as ampoules, and low heat-fed meat is a problem.

This method has low productivity and low thermal efficiency due to non-continuous workability, and in case of radiation sterilization, it is also a problem for humans due to radioactive residues, and due to high sterilization cost and most processes are not continuous, workability is inferior. Low efficiency poses a problem.

The present invention relates to a sterilization apparatus for sterilizing liquid and semi-liquid foods and medicines using a microwave dielectric heating method to solve the above problems, which will be described in detail with the accompanying drawings.

The microwave chamber 3 is installed in multiple directions in the longitudinal direction adjacent to the front and rear, and the magnetron 34 and the waveguides 32 and 33, which are microwave generators, are mounted on one side of the chamber in the upper and lower sides or on the left and right sides (the main body) The first chamber is a vertical field radiation waveguide 32, and the next chamber is a horizontal field radiation waveguide 33 so that the radiation field directions of waveguides disposed between adjacent chambers are perpendicular to each other. And alternately attach a sleeve ring (30) to the communication tube passage wall between the adjacent chambers, and the communication tube (31) made of Teflon, PE tube or glass tube of low dielectric constant inside the chamber. The sleeve ring 30 is installed in the longitudinal direction of the furnace chamber to form a microwave multistage chamber, and the outgoing motor 101 is attached to the inlet hopper 1 of the sterilization target inlet A. The sterilization object can be sent to the chamber through the discharge hose 102, and a double tube heat exchanger (2) consisting of inner and outer tubes is installed at the entrance of the discharge motor (101) and the microwave front chamber (3). At the outlet of the microwave termination chamber, a delay tank (4) having small delay tanks (41) (42) and a three-way valve (43) is installed, and the sterilant discharged from the delay tank (4) to the sterilant outlet (B). The heat exchanger (2) system constitutes a sterilant storage tank (5) of the sterilization outlet (C) cooled through the outer tube of the double tube heat exchanger (2).

In the drawings, reference numeral 10 denotes an input hopper support, 201 denotes a metal tube inside the heat exchanger, 202 denotes a coupling metal tube, and 50 denotes a storage tank pedestal.

Looking at the operation process of the present invention configured as described above, when the sterilization object is introduced into the input hopper (1) by the delivery motor 101 the sterilization object through the delivery hose 102 to the inner tube of the double tube heat exchanger (2) After being preheated, it is introduced into the chamber 3 through the communication tube 31 at the inlet of the chamber 3.

The sterilization object transported through the communication tube 31 into the chamber 3 is heated by microwave electromagnetic waves in the chamber 3 until the final stage chamber 3 is reached. In order to ensure that the sterilized material is transferred to the delay tank 14, the suspension is suspended until it is completely sterilized in the delay tank and then discharged from the delay tank 14.

At this time, the small delay tank (41) 42 in the delay tank is a material that is easy to sterilize for controlling the stagnation time to pass through only one small delay tank (41).

Through the sterilization valve 43 discharged from the delay tank is sent to the sterilization storage tank (5) via the outer tube of the double tube heat exchanger (2).

Passing through the sleeve ring 30 when the communication tube 31 passes through the walls between the chambers 3 is to suppress the interference of microwave electromagnetic waves between adjacent chambers and between the chamber and the outside.

In addition, the microwave waveguide between the adjacent chambers 3 is orthogonally mounted to reduce the mutual frequency interference between the adjacent chambers.

In this way, the sterilization target is introduced into the hopper (1), so that all the process of sending the sterilization to the sterilization storage tank (5) is made continuously.

In order to increase the sterilization capacity, the sterilization apparatus of the present invention as shown in Figures 2 and 3 can be composed of two sets of left or right, left and right, up and down four sets of sterilization apparatus of large capacity.

In this way, the present invention ensures that all sterilization processes are continuously performed in sterilizing liquid and semi-liquid foods and pharmaceuticals, and in the process of cooling the sterilized sterilants, the sterilized substances and the sterilized objects are reversed. In order to preheat the sterilized object by flowing in the direction, it is possible to further reduce the heat loss, to obtain the effect of cooling the sterilized product, and to adjust the sterilization temperature arbitrarily. You can target.

Especially in the case of fermented or matured foods, sterilization of the homo-bacteria with high efficiency sterilization can significantly extend the shelf life of the food.

Existing sterilization apparatus is difficult to expand the scale, but the sterilization apparatus of the present invention consists of more chambers in the longitudinal direction or the chamber configured in the longitudinal direction in two stages in parallel to the left or right, or up and down, right and left 4 However, if the chamber is configured in parallel, a sterilizer of higher capacity can be configured.

The design of the present invention is smaller than the conventional sterilization method, so the installation area is small, continuous and automatic operation, which saves manpower and energy, so that the sterilization cost is low and good sterilization is possible.
