Abstract
A conveyor belt for foodstuffs, especially for use in machines for preparing foodstuffs, which contains a needle punched non-wowen fabric impregnated with a binder compound.
Description
. CA 022~7143 1998-12-01 , Co~v~yor belt for food The invention relates to a conveyor belt for food, especially for use in machines for food treatment, as is applied e.g. in bakery mach;nes. In addition, the invention is also to relate to cG--veyor belts used in machinec for the processing or treatment of other foodstuffs in industrial plants for processing sweets, meat, fish etc.
Using as an example the application of a conveyor belt in bakery mach;nes for transporting dough pieces, e.g. in so-called dough forming or dough cutting mach;nes, it is common, according to the state of the art, to use co--veyor belts made of cotton fabrics or cotton felts. The belts have the task of receiving dough pieces from molds and releasing them at interchange or release points. At the release point with sharp rerouting, the dough pieces are conveyed around rerouting knife edges with radiuses of approximately 6 mm. A disadvantage of the cotton fabric or cotton felt conveyor belts used up to now is that -according to the consistency of the food parts to be transported - they have an unsatisfactory detAç~h;lity at the interchange points and also a disadvantageously large amount of elongation of the cotton fabric conveyor belt even after only several hours or days of use, which eventually leads to the unserviceability of the belt.
Furthermore, rem~;n~srs of food sticking to the belt, e.g.
through oil, fat, sugar, blood, or compo~ents of meat and fish, provide conditions enabling a bacterial invasion which would be extremely critical with regard to hygiene.
The cotton material permeated with organic components of the transported food provides a culture medium in which the bacteria can settle lastingly and multiply. Thus, the hygienic conditions for using such a co..v~yor belt in the food sector are called into question or strongly restricted. This further leads to a disintegration of the .
CA 022~7143 1998-12-01 cellulose-contA;n;ng fibers due to bacterial infestation and thus results in considerable losses in the strength of the belt. In addition, cotton fabric col.-veyor belts without binder equipment, especially those for bakery mach;nes, must be produced individually for the particular machines in guestion with regard to their length and width in endless production. This production process is time-consuming and expensive, for which reason the often unsatisfactorily short life-time of such col~vayor belts is considered to be a substantial disadvantage.
Based on this state of the art, it is the object of the present invention to provide a considerably improved cG..veyor belt for food, especially for use in mach;nes for food treatment, which avoids the above mentioned disadvantages and difficulties, has a considerably longer life-time at lower production costs, prevents or strongly reduces the settling or nesting of bacteria, and which, especially when used in bakery machines, has a considerably improved dough detachability and at least significantly reduces harmful elongation during use.
This object is achieved according to the invention in a conveyor belt of the kind stated above in that it contains needle-p~nche~ web fabric impregnated with a binder compound. Due to the velour-like well-closed surface and the correspo~;ng considerably reduced dynamic friction coefficient, the co.~-veyor belt according to the present invention is, very advantageously, well able to receive and release food parts and especially dough parts at interchange points of the machine. Due to the method of production with needle-p~nche~ web fabric, equipped with an impregnation by a binder compound of a plastics dispersion, a high inner strength of the cG.~veyor belt is achieved while the elasticity is maintained, which guarantees a low level of elongation of the material and a ,_ _ . . . . . , . .. ~ ..
CA 022~7143 1998-12-01 long life-time. This can further be promoted by incorporating a tension support in the form of a woven fabric. Since the components of the cG~.veyor material -fibers and binders - consist of plastics polymers, the possibility of bacterial decomposition of the belt is eliminated and the settling or nesting of bacteria on the whole is reduced. This has a positive influence on the hygienic conditions when applying or using such belts in machines for food treatment. Furthsr~ore, this material can be washed and disinfected with both acidic and alkaline cle~n; ng agents.
In addition, the conveyor belt material can be produced as rolled stock, on reels, i.e. the complicated production of endless material can be avoided. The rolled stock can then, ;nexrsnsively and without long delivery periods, be used to manufacture endless belts of individual length and width, which can be made endless without a large effort e.g. by finger splicing and/or gluing.
Thus, new areas of application can be opened in the food processing industry by modifying the product according to the present invention, not only in the field of bakery machines, but also in any other fields of food processing, e.g. in the processing of meat, sweets, c~nne~ fish, etc.
Due to its high strength and simultaneous high elasticity, the co~-v~yor belt for food according to the invention can be used without a problem in arrangements with knife-edge belt rerouting, whereby small rerouting radiuses of e.g. up to 6 mm can be used without a problem.
An effective embodiment provides that the impregnation is preferably a full bath impregnation.
CA 022~7143 1998-12-01 This process is relatively uncomplicated and guarantees a homogeneous distribution of the binder compound used for impregnation in the material of the co.~vayor belt.
Advantageously, the needle-pllnche~ web fabric herein consists of synthetic, natural and/or regenerated fibers and preferably of PES (polyester).
The invention further provides that the binder compound consists of natural and/or synthetic latex and especially of a carboxylated butadiene-acrylonitrile copolymer, which causes the hydrophilicity of the surface.
Effectively, the proportion of binder compound herein is between 40 and 90 wt-%, preferably 75 wt-%. Accordingly, the fiber proportion amounts to between 10 and 60 wt-%, preferably 25 wt-%. The necessary characteristics with regard to strength and elasticity can be adjusted in the desired ~; n~ions by means of a balanced relation of binder compound and fiber proportion, and of a fabric of polyester monofilaments.
The invention further provides that the conveyor belt has a characteristic tensile force of 2 2 N/mm at 1% elongation.
Advantageously, the surfaces of the con~eyor belt are hydrophilic and at the same time permeable to air.
Furthermore, the col.~eyor belt is advantageously also made resistant to oil, e.g. by a suitable choice of the components. A largely well-closed surface can herewith be achieved as a result of air-permeability, hydrophilicity and elasticity, due to which the ability to receive and release foodstuffs such as dough pieces at the interchange points of the machine is significantly improved compared to the state of the art. Especially using a fiber/binder ratio of 1:3, a high inner strength of the co--veyor belt material is achieved, which guarantees a low amount of elongation CA 022~7143 1998-12-01 during use and a long life-time and at the same time considerably reduces the rllnn;ng costs. Above all, extremely disadvantageous delays due to failure of the belt are avoided.
As suitable filling materials, the conveyor belt can contain e.g. chalk, china clay, alumina and/or titanium dioxide. Suitable color pigments can be of both organic and inorganic nature.
The thickness of the col-ve~or belt is advantageously between 1 and 3 mm, preferably 1.5 mm.
The present invention is explained in the following with the help of an embodiment example:
Needle-punched web fabric, consisting of polyester fibers with a weight per unit area of approximately 330 g/m2, full bath impregnated in a foulard with an a~ueous binder compound, consisting of carboxylated butadiene-acrylonitrile copolymer, and cont~; n; ng filling material and/or coloring pigments for coloration, is dried with a binder dry add-on of 1000 g/m2 at temperatures of beL.~Qn 100 and 140~C. After the drying process, the preproduced belt is emerized on both sides with corundum wheels, preferably with a grain size distribution of 120, to a final thickness of between 1 and 3 mm, preferably 1.5 mm.
The resulting velour-like smooth surface areas have largely well-closed surfaces which are at the same time air-permeable, hydrophilic and smooth and which have a dynamic friction coefficient of ~ = 0.22.
The structure of the conveyor belt according to the present invention comprises a needle-p~nc~e~ web fabric consisting of 100% polyester fibers with a fiber titer of 1,7 dtex and a staple length of preferably 40 mm, needled with a needling density of 450 needle holes/cm2 and having a CA 022~7143 1998-12-01 .
weight per unit area of e.g. 330 g/m2, and a woven fabric, e.g. of polyester with 160 g/m2, full bath impregnated in a foulard with an aqueous binder compound, consisting of e.g.
55 wt-% carboxylated butadiene-acrylonitrile copolymers, 42 wt-% chalk as filling material, 2.8 wt-% coloring pigments for coloration, and 0.2 wt-% dispersing agents, with a binder dry add-on of 1000 g/m2, emerized on both sides to its final thickness after the drying process.
The completed co.veyor belt has the following characteristics:
- a well-closed surface and thus avoidance of bacterial attack and/or hypomycetes;
- air-permeability and thus impro-v~- -nt of the detachability of the transported food parts;
- hydrophilic surface, promoting the drying process and thus also improving det~c~hility;
- good cle~n;ng possibilities because belt can be washed and disinfected;
- resistance to fat and oil;
- long-term thermal stability up to ca. 100~C;
- fulfillment of the legal norms for use in food transport.
The conveyor belt according to the present invention optimally achieves the object stated above.
