Abstract

PROBLEM TO BE SOLVED: To provide high antibacterial mildewproof performance by including an antibacteral mildewproof agent composition using (±)l-[2-(2,4- dichlorophenyl)-2-(2-(propenyloxy)ethyl]-1H-imidazole(Imazalil) as an effective component in a resin layer and an adhesive treating agent. SOLUTION: A polyether polyurethane resin (polytetramethylene ether glycol) is pelletized, Imazalil is added to this to be dryly blended, and this blend is heated to be extruded in a sheet shape by an extruder to manufacture a sheet having a thickness of 0.3 mm. An extruded sheet of the polyurethane resin obtained in this way and polyester canvas by impregnating/sticking an adhesive treating agent are superposed to be pressurized/laminated by a funnel cure method while heating these members at a temperature of 150 to 180 deg.C to manufacture a food carrying belt of the single constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin belt for conveying food, which can convey food in a naked state.

[0002]

A resin belt for food transport used as a conveyor belt for transporting food in a food manufacturing plant or the like is a problem in that microorganisms multiply because residues of food, which is a transported material, adhere to the surface. And the quality and preservability of food may be impaired by microorganisms. For this reason, at the food manufacturing plant, the belt is washed after the work is completed, but when removing microorganisms completely, use high-concentration chemicals such as sodium hypochlorite and hydrogen peroxide. It was necessary to perform cleaning for a long time, which required a large amount of labor for hygiene management.

[0003]

SUMMARY OF THE INVENTION The present invention provides a resin belt for conveying foods having high antibacterial and antifungal properties which solves the above problems.

[0004]

BEST MODE FOR CARRYING OUT THE INVENTION Imazalil used in the present invention has a chemical name of (±) 1- [2- (2,4-dichlorophenyl) -2- (2-propenyloxy) ethyl]-.
1H-imidazole is an antibacterial and antifungal agent approved as a food additive, and is also used in the form of sulfate, nitrate and the like. In the present invention, the use of the imazalil drug substance is preferred.

[0005] The food transport belt is formed by laminating a resin layer on the surface of a core layer formed by impregnating an adhesive treatment agent into a core canvas, and the surface layer is a transport for transporting food. Surface. In the present invention, a food transport belt is manufactured by incorporating imazalil into the resin layer on the surface. It is preferable that the imazalil is also contained in the bonding agent for the core layer.

[0006]

The food transport belt described in the above is a one-ply belt, in which an intermediate resin layer is laminated between two core layers formed by applying an adhesive agent to a core canvas and Laminate a resin layer that will be the transfer surface on the surface of the core layer of
It can also be formed as a two-ply belt composed of two resin layers and two core layers. Also in this two-ply food transport belt, the surface resin layer contains imazalil.

In the food transport belt according to the present invention,
As a resin forming the resin layer, a polyurethane resin, a vinyl chloride resin, a polyolefin resin, or the like can be used.

Further, as the adhesive treatment agent for impregnating and adhering to the above-mentioned core body fabric, a liquid material containing a polyurethane resin as a main component, and adding and stirring a solvent for dissolving the polyurethane resin can be used.

The amount of imazalil added to the resin component of the resin layer and the adhesive agent is preferably in the range of about 0.01 to 1.0% by weight.

[0010]

By including imazalil in the resin layer and the adhesive treatment agent, it is possible to produce a resin belt for conveying foods having antibacterial and antifungal properties.

[0011]

The present invention will be described below in detail with reference to examples. But,
The present invention is not limited to these examples.

Example 1 A polyether-based polyurethane resin (polytetramethylene ether glycol-based) was pelletized, imazalil was added thereto, followed by dry blending. The mixture was heated, extruded into a sheet by an extruder, and extruded into a sheet having a thickness of 0. A sheet of 0.3 mm was produced.

A mixed solvent of dimethylformamide and toluene is used in an amount of 850 based on 100 parts by weight of the polyether polyurethane resin (polytetramethylene ether glycol).
Parts by weight, a dip solution to which imazalil is added, a polyether-based polyurethane resin (polytetramethylene ether glycol-based), 100 parts by weight, 400 parts by weight of a mixed solvent of dimethylformamide and toluene, and a paste liquid to which imazalil is added. An adhesive treatment agent is prepared, and first, a polyester canvas is immersed in a dipping solution, and the dipping solution is
After impregnation at an impregnation amount (solid content conversion) of 150% by weight,
After drying at a temperature of 160 ° C. for 30 to 60 seconds, a size liquid is applied to the surface of the dipped polyester canvas with a doctor knife, and the size liquid is applied and impregnated at a weight of 20% by weight (in terms of solid content). At a temperature of 150 to 160 ° C. and 30 to
The polyester canvas was treated with an adhesive treatment by drying for 60 seconds.

The extruded sheet of the polyurethane resin obtained as described above and the polyester canvas impregnated with an adhesive agent are superimposed, and are laminated under pressure by a roto-cure method while heating at a temperature of 150 to 180 ° C. As a result, a one-ply belt for conveying food was produced.

The food transport belt produced as described above was cut to prepare a test piece having a size of 40 mm × 40 mm, which was used as a sample for an antibacterial test and a fungicide test.

The food transport belt of the present invention obtained in Example 1 was subjected to an antibacterial test using Escherichia coli and Staphylococcus aureus according to the halo method (JIS-L1902). The food transport belt of the present invention to which imazalil is added in an amount of 0.05% by weight, 0.1% by weight and 0.2% by weight has an antibacterial effect on both the resin layer and the heart layer against the above two kinds of bacteria. Indicated.

Next, an example of a fungicide test will be described. The food conveying belt of the present invention obtained in Example 1 was subjected to a halo method (JIS-Z2
911), according to Aspergillus niger
FERM S-1, Penicillium ctr
inum FERM S-5, Cladosporiu
