Abstract

The task was to find a hygiene regime for Transportbaender, especially for Eiertransportbaender that allows the use of certain cleaning and microbicidal agents, the maintenance of a low germ level on Eiertransportbaendern. The object is achieved according to the invention by a special combination of known cleaning and microbicidal agents, each used alone, do not have sufficient effect, but unfold in the combination a resounding effect, solved to a special hygiene regime for Eiertransportbaender. Particular advantages of this hygiene regime are above all: ease of use, use of low-toxic and low-polluting agents, good material compatibility, low corrosiveness, feasibility even in occupied stalls, no influence on the quality of food. It was found that per 100 m band length about 10-50 l fluid volume are required, the use of a dipping belt with mechanical cleaning component is advantageous. According to the invention, the hygiene regime consists of the following sub-processes: 1. Pre-soaking, 2. Cleaning, 3. Sanitizing cleaning, 4. Reworking. {Hygiene regimes; Transportbaender; Eiertransportbaender; cleaning and microbicidal agents; Germ level; User-friendliness; material compatibility; to soak; Clean; Hygenic cleaning; rinse}

Description

User-friendliness, use of low-toxic and low-polluting agents, good material compatibility,

low corrosiveness, feasibility even in occupied stables, no influence on food quality.

It was found that per 100 m tape length about 10-501 liquid volumes are required, the use of a Dipping tape with mechanical cleaning component is advantageous. According to the invention, the hygiene regime consists of the following sub-processes:

1. Avoid

2. Clean

3. Hygienic cleaning

4. Rinse

The following active ingredient combinations have proven to be particularly effective:

1. Pre-soaking and cleaning

For the pre-soaking and cleaning are combinations of anionic and nonionic surfactants z. B. from ethoxylated glycols or alkylphenols in concentrations of 10-20% and anionic surfactants such as alkyl sulfonates or alkylbenzenesulfonates in concentrations of 15-30%, as used in conventional detergents in concentrations of 0.5% to 2% suitable. (Solution A)

2. Hygienic cleaning

For the sanitizing cleaning process according to the invention alkaline adjusted phosphate and / or silicate-containing solutions of peroxo compounds such as hydrogen peroxide and / or performic or peracetic acid in concentrations of 0.05-1.5%, preferably 0.1-0.5% used from powdered! Mixtures of peroxo compounds, phosphates, silicates and surfactants with activators, such. B. 1,5-diacetyl-2,4-dioxo-porhyaro-1,3,5-triazine (DADHT), in aqueous solution of 30-00g / l powdery total mixture is formed, wherein at least 10g peroxo compound and at least lOg DADHT are required , (Solution B) For the further stage of germ reduction, especially in epizootic diseases or animal disease control, it is advantageous, in addition with 0.5-1.0% solutions of a mixture of 5-22% formaldehyde, 5-20% Olutardialdehyd and After-treatment 5-10% benzalkonium chloride or methalconium chloride. (Solution C) By combining the chemical principles of action, which alone in no case have a sufficient effect, it; aqueous solution of + 5-4O ⁰ C, preferably + 15-25 ⁰ C followed by rinsing with water, the solutions A to C are changed after each band pass, can be with high efficiency (low cost, high efficiency, high user friendliness ) achieve the required cleaning and disinfecting qualities. The control takes place on the egg belt and in the dipping bath as well as microbiological (eg after methods of the TGL 37768/04)

3. Rinse

To remove the remainders, rinse with clean water. By combining the chemical principles of action, which alone in any case a sufficient sanitizing effect

own, can be achieved with high efficiency (low effort, high efficiency, ease of use, low corrosion) at temperatures from + 1O ⁰ C, the required cleaning effect and the germ-reducing effect.

It is particularly advantageous that during and after carrying out the sanitary cleaning a contamination

other non-treated areas with plant-specific germs is prevented.

In case of epidemic danger and the occurrence of epizootics it is advantageous to carry out the law

prescribed disinfection to perform a sanitary cleaning invention, as a result dienachfolgenden disinfection acts particularly resounding.

The control is carried out according to customary microbiological methods.

Implementation of the hygiene regime

For the following examples, the egg transport belts were cleaned using the comparative preparations V1-V3 or the solution according to the invention alone or in combination with one another. In each case was rinsed (N). The sanitizing Effeli was determined by means of Abklatschpräparaten. The results are shown in Table 1.

B. 1.5 diacetyl-2,4-dioxo-perhydro-1,3,5-triazine (DADHT) in addition to phosphates, silicates and surfactants are used in step 1. 2. Hygiene regime according to claim 1, characterized in that in a stage 2 on special occasions, such as occurrence or danger of epizootic additionally 0.5-1% solutions of mixtures of 5-22% formaldehyde, 5-20% glutaric dialdehyde and 5-10% benzyl or methalconium chloride and then rinsed with clear water. Field of application of the invention The invention is used for cleaning and maintaining a low germ level of conveyor belts, in particular of Eiertrai isportbändern in the laying hen husbandry and Frischierproduktion in intensive care for use. Characteristic of the known solution The cleaning and germ reduction or disinfection of conveyor belts, in particular egg conveyor belts, is carried out as part of the normal cleaning and disinfection measures. Special rules and methods for cleaning and disinfecting egg conveyor belts do not exist. Usually, cleaning and disinfection takes place during the scheduled shutdown (service) period. In the process, some of the systems and also the egg conveyor belts are dismantled, cleaned and disinfected. This process is very labor intensive and time consuming. Particularly disadvantageous is due to the heavy contamination required use of highly corrosive cleaning agents such as sodium hydroxide solution u. Ä. A sufficient sanitizing cleaning with Keimminderung is not achieved despite the use of such detergents with reasonable effort. Subsequently, a disinfection of the egg transport belt is required. The disinfection methods used for this purpose, such as spray disinfection, aerosol disinfection or formaldehyde evaporation, are very time-consuming and require comprehensive health and safety measures to avoid damaging the health of the employees. A cleaning and disinfection of egg transport belts during the period of maintenance of chickens is not feasible with the usual cleaning and disinfecting agents or methods. In order to reduce the risk of infection, it is urgently necessary to permanently reduce the number of micro-organisms, especially on the egg conveyor belts, in order to exclude risks to human and animal health and to maintain productivity in cost-intensive facilities. Object of the invention The aim of the invention was the development of a working time-saving hygiene regime for conveyor belts, especially for Eiertransportbänder, whereby the ever-present bacterial load is reduced so much that virtually no risk of infection is more and their implementation even during the period of keeping chickens without Nr.oenwirkung on humans, animals and Eggs is possible. Explanation of the essence of the invention The task was to find a hygiene regime for conveyor belts, in particular for egg conveyor belts, which allows the use of certain cleaning and mikrcbizider means compliance with a low germ level on the egg conveyor belts. The object is achieved by a spezieile combination of known cleaning and microbicidal agents, each used alone, do not have sufficient effect, but unfold in the combination a resounding effect, to a special hygiene regime for Eiertransportbänder solved. Special advantages of this hygiene regime are above all:
