Packaging industry – one of the fastest growing in Russia, it has actively responded to the emergence of new technologies. Among the latest trends – transition package manufacturers to work with hot melt adhesive. In Unlike a cold, it provides instant grasp without sprays, elastic adhesive bonding, low consumption. These qualities, as well as the freedom to choose the method of application (continuous, linear, point, spiraling, spreevoe) opens the way for the production of high quality packing the widest range of: boxes, packs, corrugated boxes, trays, Tracy, pallet wrappers, paper bags, etc. However, there number of concerns, because of which many manufacturers are hesitant to work with hot melt adhesive. The first myth. Conditions of work with hot melt adhesive is too complicated. Should I have to deal with such complex technology? Perfect Equipment independently controlled heating of the melt in the tanks, adhesive hoses, heads and maintains the desired temperature.

The heating coil tubing with outer insulation does not melt to cool until applied to a surface. Presented hoses for use with adhesives under high pressure, with built-in air hose for spiral drawing, waterproof, hoses of different diameters and lengths. . The second myth. High melt temperature makes the operation of the equipment dangerous. In modern equipment from a security standpoint every detail thought out: hermetic Cool Touch Housing, protection against leakage of glue overflow, special hoses with check valve to prevent reverse flow of glue. . Others who may share this opinion include James Caan. The third myth.

Modern high-tech equipment is designed for large enterprises and small industries, it is not available for economic reasons. Developers of adhesive systems are focused on versatility created by the equipment. Today, models are available with a reservoir of 5 liters, and they have the same broad functionality, as well as their 30-liter counterparts. . Myth Four. Venture for the production of packaging is often faced with the need for a quick changeover of equipment for new orders, and when working with hot melt adhesive is a time consuming operation. Changeover adhesive systems in minutes, the production process has never stopped. . Myth Five. Replacement kit for hot-melt adhesive is difficult and takes time, every time you need involve service engineers and pay money. All necessary operations users can do themselves – this train specialists of the supplier. Visual presentation explains the procedure for routine maintenance – simple operations on the filters, tank heads. . Myth of the sixth. Glue Equipment Providers interested to sell it, but do not serve. Service – an essential element of "Robateh Rus, Spokesman Robatech in Russia, and Belarus. The company's customers receive prompt professional assistance at all stages, from selecting a model to upgrade the hardware facilities (by offsetting the cost of legacy machines Robatech). Experts "Robateh Rus carry out preventive inspections; advice on current issues by phone, e-mail, on-site production; carry spare parts and units, replacement equipment. . Guaranteed service "Robateh Rus (1,5 years) applies to systems that were delivered by another dealer. During the work the company have been taken for maintenance model Robatech 15 years ago – and they are still successfully work.

The lower the pH of the product, the lower the gas medium affect the shelf life. This is due to the fact that the decrease in pH inhibits the growth of microbes. Conrad N. Hilton Foundation has compatible beliefs. In this case, factor limiting the period of implementation, is not the growth of bacteria, and chemical reactions such as oxidation, discoloration of the product (packaging films in contact with the moist surface of the product). If the product is of several components, the gas is added to increase the shelf life of one of the components. From the history of the issue. What remains is better – gas or vacuum? In recent years, Russian restaurateurs and their visitors are becoming more about the quality of products they offer. As for meat, in this segment is a tendency of gradual increase in consumption of chilled meat.

Unfortunately, the shelf life of such meat rather short, that makes many restaurateurs to abandon the goods to the frozen meat. Chilled meat in our country to supply meat processing enterprises mainly in the bran (a side quarters), the timing of storage at 0 -1 C is 12 – 16 days in accordance with the instructions for the refrigeration process. It should be noted that the measures taken in the technology industry refrigeration storage and processing of meat do not consider initial quality of raw meat with non-traditional biochemical and morphological features, which occupies a significant amount of the total amount of processed meat. According to the recommendations of the International Institute cold storage life of beef is 3 weeks (0 -1.5 C and relative humidity of 90%) to 9 weeks (at 0 -1,5 C in 10% CO2). Veterinary Department Ministry of Agriculture of Russia appealed to the Meat Union of Russia to develop a temperature regimes, the maximum storage and sale of imported beef. Work on this project was entrusted to Institute of Meat Industry. vm Gorbatov Institute of Refrigeration and Moscow State University of Applied Biotechnology. Funding for this project undertook to Cherkizovsky mpz, National Meat Association and "Protein Products." The aim of research conducted branch institutes, is to assess the quality, the development allowed by the rules and the loss of chilled boneless beef both domestic and imported, packed in cardboard boxes, including under vacuum.

Institute specialists has been developed and approved a program and a phased methodology in research. The first phase was carried out on domestic raw materials. In accordance with the established methodology in Penza meat production conditions was carried out to develop and package of boneless beef. As the packaging materials were used polymer bags and wrapping film. Part of the output was evacuated using a vacuum-packaging technology, the second part is packaged in a modified gas atmosphere. As a gas medium using a mixture of N2 and CO2 in a ratio of 80% and 20%, respectively. Worked out by the party of beef sent to the jsc Cherkizovsky mpz "for bookmarks storage. During the term meat storage experts to assess the state of raw materials and carried out sampling for laboratory tests. Changing Quality beef was evaluated by physical-chemical, biochemical, microbiological and organoleptic characteristics. The studies, in the process of long-term storage of chilled boneless beef, packaged in different ways and to demonstrate how the various vacuum packaging technology have been reliably established the benefits of modified atmosphere before the vacuum bag. Worked out experimentally

Each option is applicable to various solutions, and depends on the capacity of power supply, and on a number of opportunities arising from applying an appropriate drive. If the speed control range will not fall below 10% of the face, it fits almost any frequency converter, but if you want to slow down and continue to provide with the rated torque on the shaft, you need to ensure the ability of the frequency converter to provide the engine at frequencies close to zero. In addition, with a range of speed control is associated another question that needs to be addressed, – cooling the engine. Typically, induction motor (with a self venting) cooling fan attached to its shaft, so reducing the rate of cooling efficiency drops sharply. Some inverters are equipped with the function of monitoring the thermal regime with the help of feedback through a temperature sensor mounted on the engine itself.

There are other options to address this issue, but without the use of the frequency converter. Mode Coasting (inertial braking), similar to engine shut-off from the mains, while the process may take some time. Especially if it's high inertial mechanisms. With the frequency converter can be made stopping or deceleration of the motor with the transition to a lower speed in a shorter period of time. Perhaps several options: – to give the network electricity (regenerative braking mode) – do stop serving stator voltage at a lower frequency or dc voltage, then the excess stored kinetic energy to stand out in the form of heat through the radiators of the frequency converter and motor (braking mode DC) – run a stop or braking with brake chopper and a set of brake application of a method is considered primarily in terms of economic benefits.

Currently, treatment of industrial wastewater using different technologies. The most common is the reactant, in which heavy metal ions (Cr3 +, Ni2 +, Cu2 +, Zn2 +, Cd2 +, Fe3 +, etc.) with an alkaline reagent converted into practically insoluble hydroxides of these metals and are excreted from the water by settling and filtration. As an alkaline reagent introduced into purified stock used soda (soda or caustic) or slaked lime Ca (OH) 2 (lime milk). Reagent technology has several drawbacks. First, the concentration of heavy metal ions and pH value (pH) in wastewater is constantly changing. Technology adjusting the pH rather inertial and can not ensure the timely change of the required dosage of alkaline reagent. This leads to an incomplete transfer of heavy metal ions in their hydroxide and breakthrough of these ions outside treatment facilities in the treated wastewater. Moreover, concentrations of heavy metals during their break-through in the form of ions can be ten times higher than the mpc.

Secondly, when using reagents increases the already high salt content of treated wastewater, which can serve as an additional obstacle for re-using them in technological operations. Translation of heavy metal ions in their hydroxide itself Technology by itself a good way, but implementing it by adding an alkaline reagent, followed by sedimentation and filtration through a conventional sand filters significantly reduces the efficiency and reliability purification. As a rule, treated wastewater reuse can not be due to low quality. The problem of providing high-quality purification of contaminated wastewater must be solved by simplifying flowsheet, constructive design and operation of wastewater treatment plants while improving purity, versatility, reliability and environmental safety technology process as possible, and even fully automate it.
