Small dry ice pellet making machine

In life, dry granules are used in tire companies, printing companies, engine repair companies, and other industries, mainly for dry ice blast cleaning, and also for a wide range of applications in the refrigerated transport, catering and entertainment industries, but many friends, However, it is not necessarily know how the dry ice is made. The following small dry ice machine is a brief introduction for everyone:

First of all, the concept of dry ice is needed. At room temperature, when the carbon dioxide gas is pressurized to about 101,325 Pa when a part of the vapor is cooled to about -56 ° C, it is frozen into a snow-flaked solid carbon dioxide. Solidified carbon dioxide has a large heat of vaporization, which is 364.5 J/g at -60 ° C. When gasified under normal pressure, the ambient temperature can be lowered to about -78 ° C, and no liquid is produced, so it is called "dry ice".

The dry ice medium used in dry ice blast cleaning is a dry ice granule produced by a dry ice pelletizer. These dry ice granules can be used immediately or stored in an incubator for later use. These particles are typically 3 mm in diameter and 2.5 mm to 10 mm in length. In this way, the high-pressure liquid CO2 is ejected from the pipe and converted into a snow-like solid CO2, and the snow-like CO2 is extruded into dry ice particles by a mold pressure.

Granular dry ice is a by-product of industrial processes, such as fermentation processes and petroleum refining processes, which produce by-product CO2. The CO2 produced in these production processes is purified, hydraulically and stored, and dry ice is produced for cleaning. When the CO2 sublimate is discharged into the atmosphere during the injection process, no new CO2 is produced, but the original CO2 by-products are discharged. It realizes the reuse of exhaust gas CO2 for the benefit of mankind.

Dry ice making machine

The dry ice blasting system can be generally divided into two parts: one is a dry ice preparation system, which is used to make liquid CO2 into a certain specification of dry ice granules or dry ice cubes; the second part is a dry ice blast cleaning system, which is specially formulated by the system. The air compressor or the compressed air generated by the compressed air system formulated by the factory itself, the prepared dry ice particles or dry ice cubes are filled in the cleaning equipment, and the high-density dry ice particles or fine powder are driven by the compressed air. Compressed air impinges on the surface of the object being cleaned, thereby cleaning.

It can be applied to clean electric boilers, condensers and various heat exchangers. It also directly loads indoor and outdoor transformers, insulators, power distribution cabinets, and wire and cable. It is difficult for the printing industry to clean inks, and ink products on gears and rails cause poor print quality. Dry ice blasting removes a variety of oily aqueous inks and varnishes, as well as clean oils, inks and dyes on gears, guides and nozzles. Reduce time and eradicate the use of hazardous chemicals to avoid the discharge of hazardous wastes and solutions, as well as damage from hazardous solvents. 3. Dry ice is used in the industry. Some dermatologists use dry ice to get acne.

In order to protect the ozone layer, the Foreign Economic and Technological Office of China's State Environmental Protection Administration promoted the replacement of ODS in the cleaning industry. The PCE and TCE used by most dry cleaners became the transitional choice. It is hoped that the choice of dry cleaning solvent and washing process not only needs to meet the corresponding environmental specifications, but the complete recycling of solvent has become the goal of green dry cleaning. That is, dry cleaning clothing must not contain harmful substances that cause harm to the human body and environment. There are potential factors that can cause harm to the human body. However, PCE and TCE are chlorinated olefin compounds, which can cause damage to the liver. Metabolites can cause fat metabolism disorders, and PCE harmful events have occurred in some dry cleaning places. Therefore, Shuliy Sida Dry Ice Cleaning Service has become an alternative method for the apparel industry.

The dry ice blasting system can be used as a system for assembling the dry ice preparation system together with the dry ice blasting system. The dry ice preparation system can also be separated from the dry ice blasting system. The dry ice preparation system is only used as a raw material production equipment. The dry ice blasting system is used alone. For cleaning projects.

Complete dry ice blasting systems include liquid carbon dioxide storage systems, dry ice manufacturing systems, dry ice storage transportation systems, compressed air supply systems, jet cleaning systems, and connections between systems.

Vegetable cutting machine operation process

It is very necessary for the safe use of the vegetable cutting machine. If the vegetable cutting machine is dangerous during the operation, Zhengzhou Lange Machinery will introduce the operation process of the vegetable cutting machine.

The correct use and safe operation of the vegetable cutting machine are clearly stated in the manual, and there are also notice labels on the machine, which are generally very obvious. Why are there many users who have been injured?

So no matter what kind of vegetable cutting machine, don't take it lightly, you must operate safely according to the regulations, there will be no problem.

Vegetable cutting machine operation process:

1. When cutting vegetables, do not put your hand into the centrifugal roller, dial or under the vertical knife after starting the vegetable cutting machine. Do not put your hand into the pressing belt, and press the vegetable belt for a certain safe distance. Otherwise, it is easy to be Entangled or stuck;

2, long-term use must be regularly checked whether the switch and power cord are damaged, damp, water, etc., in order to prevent electric leakage caused by electric leakage, in order to ensure safety, please connect the ground wire in the grounding mark of the machine;

3. In the process of use, if the conveyor belt and the pressing belt are loosened, the screws should be tightened in time, but pay attention to the tightness of the two sides, and do not let the belt run off;

4, the machine is kept clean, try to avoid contact with water, often add oil to the oil filling port, pay attention to the maintenance of the machine.

What is a vacuum packaging machine?

The vacuum packaging machine can automatically extract the atmosphere in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be filled with nitrogen or another gas and then the sealing process is completed.

There are many types of vacuum packaging machines available, including stretch film automatic vacuum packaging machine, air-locking fresh vacuum packaging machine, box-type continuous sealing machine, rolling packaging machine, double-chamber packaging machine, small packaging machine and according to customer requirements. A series of custom-made packaging machines, the general classification is these, if there are other specifications and models can call to communicate custom.

Stretch film vacuum packaging machine includes molding zone, vacuum sealing zone, cutter discharge, integrated into a fully automated flow program, according to the customer's product to make the most suitable mold for molding packaging, vacuum packaging, automatic cutting film Finish the finished product.
