Product Description: Imported beef can be restored to its original state after thawing, with moisture loss meeting the required conditions.1. Working principle of the low-temperature high-humidity thawing machine: It utilizes low-temperature, high-humidity circulating air passing over the surface of frozen products to achieve slow thawing under relatively small temperature differences. Air ducts circulate air under multiple air plates to blow over the thawing products, creating uniform airflow organization. A certain level of humidity increases the heat conduction medium in the air. The thawing process is fully automated and controlled in stages by a PLC microcomputer system, regulating temperature, humidity, and time (low temperature around 10°C to inhibit bacterial growth, humidity around 90%).2. Much beef is quartered, and due to its larger size during thawing, air duct circulation is used for air supply. The thawed meat is then further processed and divided.3. Currently, the most widely used, effective, and safest method for meat preservation is low-temperature treatment. Thawing involves raising the temperature of frozen meat to melt the ice crystals and restore it to its pre-frozen state. Thawing methods are divided into two categories based on heat supply: external thawing and internal thawing. External thawing involves heat transfer from a higher-temperature medium to the surface of the frozen meat, with heat gradually spreading from the surface to the center (e.g., air thawing, water thawing). Internal thawing involves simultaneous heating of all parts of the frozen meat by the medium, providing internal heating (e.g., microwave thawing, high-voltage electrostatic thawing, high-voltage radio frequency thawing).4. Our low-temperature high-humidity thawing system mainly consists of five parts: the insulated thawing chamber, air circulation system, heating and humidification system, refrigeration system, and electrical control system. Each part is designed in coordination with the thawing products, and many of our solutions are supported by data from practical applications. more>

Product Description: Q235C steel plate is a commonly used carbon structural steel with clearly defined chemical composition and mechanical properties in the Chinese National Standard (GB). According to search results, the chemical composition of Q235C steel plate is specified in the GB/T 700-2006 standard, with a carbon content not exceeding 0.17%, manganese content not exceeding 1.4%, silicon content not exceeding 0.35%, phosphorus content not exceeding 0.040%, and sulfur content not exceeding 0.040%. These components give Q235C excellent plasticity, toughness, weldability, and cold stamping performance, making it suitable for manufacturing thin plates, steel bars, and various section steels for steel structures.In the European Standard (EN), the material corresponding to Q235C steel plate is S235JR. S235JR is a non-alloy structural steel defined in the European Standard EN 10025-2:2004. Its chemical composition and mechanical properties are similar to Q235C, but specific values may differ. For example, S235JR typically has a carbon content below 0.22%, manganese content below 1.65%, and certain limits on phosphorus and sulfur content.Comparing the Chinese and European standards, the main differences between Q235C and S235JR in chemical composition lie in manganese content and the restrictions on phosphorus and sulfur content. Additionally, the mechanical property requirements of both are similar, but there may be differences in certain details, such as specific values for yield strength and tensile strength, and how they vary with plate thickness.In practical applications, if Q235C steel plate needs to be replaced with a European Standard material, S235JR can generally be used directly. However, attention should be paid to the slight differences in chemical composition and mechanical properties between the two, and selection should be made based on specific engineering requirements and standards. Additionally, considering that materials under different standard systems may have subtle process differences, it is advisable to consult relevant professionals or conduct necessary tests when substituting materials to ensure they meet engineering needs.Coil11.75mmQ235C0.01500.0128.720Coil11.75mmQ235C0.01500.0128.460Coil11.75mmQ235C0.01500.0128.650Coil12.1mmQ235C0.01500.0128.800Coil13.5mmQ235C0.01500.0128.720Coil13.5mmQ235C0.01500.0128.740Coil13.5mmQ235C99.01500.0128.450Coil13.5mmQ235C99.01500.0128.430Coil13.5mmQ235C0.01500.0128.420Coil13.75mmQ235C0.01500.0128.170 more>

Product Description: Product Introduction      The elastic three-dimensional filler selects several high-quality varieties of polyolefin and polyamide that are corrosion-resistant, temperature-resistant, and aging-resistant. Mixed with additives such as hydrophilicity, adsorption, and heat-oxygen resistance, it uses a special wire drawing and filament fluffing process to interweave and fix the filaments onto a corrosion-resistant, high-strength central rope. Due to the excellent material selection and process formulation, the filaments are arranged in a three-dimensional, uniform radial pattern, forming a suspended three-dimensional elastic filler unit. Within the effective area, the filler can fully expand in all directions, allowing gas, water, and biofilm to mix, penetrate, and exchange thoroughly. The biofilm can not only uniformly attach to each filament, maintaining good activity and variable porosity, but also achieve an increasingly large specific surface area during operation while facilitating effective metabolism. This characteristic and phenomenon are currently unmatched by other domestic fillers.  Product Features      Compared to rigid honeycomb fillers, the three-dimensional elastic filler offers greater porosity variability and is not prone to clogging. Compared to soft fillers, it has a longer material lifespan and does not adhere or clump. Compared to semi-soft fillers, it provides a larger specific surface area, faster biofilm attachment, and lower cost. Therefore, this filler can be confirmed as the fourth-generation high-efficiency, energy-saving, and innovative filler following various rigid, soft, and semi-soft fillers. Scope of Application  Widely used as a biological filler in biological contact oxidation tanks and hydrolysis acidification tanks. more>

Product Description: What is the working process of a steam generator?      The working process of the steam generator is as follows: The feed water is heated by industrial steam in the first-effect preheater, then enters and is further heated by the condensate from industrial steam in the second-effect preheater; it then enters the top of the evaporator through a water distribution device, evenly flowing into the evaporation tubes, forming a thin film of water flow inside the tubes; due to its thinness, this water flow evaporates quickly, generating secondary steam; the unevaporated feed water is discharged out of the system. The evaporated feed water, now secondary steam, continues to spiral upward within the steam generator, passes through a steam-water separation device, and is output as pure steam from the pure steam outlet. The industrial steam, after transferring heat to the feed water in the evaporator, condenses into industrial steam condensate, which serves as the heating source for the preheater. The preheated feed water is finally discharged from the non-condensable vent of the preheater. A small amount of pure steam is collected by the condensate sampler, where it exchanges heat with cooling water, condensing into distilled water; through online conductivity detection, the purity of the steam is determined.      The secondary steam converted from feed water is clean steam, undergoing three separation stages: upon initial entry into the evaporator, it flows downward along the tubes while evaporating, which is the first separation; the evaporated feed water (secondary steam) makes a 180-degree turn at the lower end of the evaporator, where impurities are separated downward by gravity, constituting the second separation; the evaporated feed water, i.e., the secondary steam, continues to spiral upward within the steam generator to a specialized separation device in the mid-upper section, where the third separation occurs.      In the feed water, there is a portion of gas that cannot condense into water, known as non-condensable gas. Depending on the level of automation control, a continuous venting device for non-condensable gases is installed at the top of the evaporator to discharge this portion of gas. more>
