Shell and tube cooler
The corn flake shell and tube cooler has good cooling effect: the shell and tube structure enables the corn flakes to exchange heat with the cooling medium through the tube wall. The cooling medium flows inside the tube and the corn flakes flow outside the tube. The two flow in reverse or forward directions, which can fully utilize the cooling capacity of the cooling medium and effectively reduce the temperature of the corn flakes. The cooling effect is stable and reliable.
Compact structure: The corn flake tube cooler occupies a relatively small area and can be flexibly arranged according to the actual situation of the production site. It is suitable for production workshops of different sizes and can effectively save space.
Easy operation and maintenance:o The corn flake tube coler has a simple structure, no complicated moving parts, and is easy to operate and maintain. The cooling tube is easy to disassemble and replace, which facilitates the inspection and maintenance of the equipment and reduces maintenance costs and downtime.
Strong adaptability: The corn flake shell and tube cooler can adapt to the cooling needs of corn flakes with different outputs and different initial temperatures by adjusting the flow rate, temperature and flow rate of the cooling medium, and has a wide range of applications.
Stable product quality: The corn flake tube cooler can accurately control the cooling speed and temperature of corn flakes, avoiding the quality degradation of corn flakes due to uneven cooling or too fast cooling, and ensuring the stability and consistency of product quality.
High safety: The cooling process of the corn flake tube cooler is carried out in a closed pipe, which reduces the contact between the corn flakes and the external environment, reduces the risk of dust flying and material contamination, and improves the safety and hygiene of production.
Long service life: The corn flake shell and tube cooler is made of corrosion-resistant materials, such as stainless steel, etc. It has good wear resistance and corrosion resistance, can withstand long-term alternation of hot and cold and material erosion, and has a long service life.
Corn flake tube cooler structure
- Tube bundle: It is composed of multiple tubes arranged in parallel and is the core part of heat exchange. The tubes can be bare tubes or with fins to enhance the heat dissipation effect.
- Shell: used to contain the tube bundle, provide flow space for cooling medium and corn flakes, usually cylindrical.
- Corn flake tube cooler tube sheet: fixes both ends of the tube bundle, separates the tube side and the shell side, and ensures that the fluid flows in their respective channels without leakage.
- Baffles: Installed in the shell side, they make the corn flakes flow in a zigzag pattern in the shell side, increasing the flow rate and disturbance of the fluid and improving the heat exchange efficiency.
- Head: Located at both ends of the cooler, connected to the shell, used to close the cooler and provide fluid inlet and outlet channels.
Working principle of corn flake tube cooler
Based on the principle of heat exchange, the corn flakes enter from the pipe inlet on the cylinder, and flow through the baffle channels in sequence to the pipe outlet in a zigzag manner. The cooling medium flows in a double-pass manner, from the water inlet through the water divider cover into half of the cooler pipe, and then flows from the return water cover into the other half of the cooler pipe, into the other side of the water divider cover and the water outlet pipe. In this process, the heat of the corn flakes is transferred to the cooling medium through the pipe wall, thereby achieving the purpose of cooling.
Corn flake tube cooler technical parameters
- Cooling area: According to actual production needs, the cooling area can be selected within a certain range, ranging from a few square meters to dozens of square meters.
- Working pressure: Generally speaking, the design pressure of the shell and tube cooler is around 0.6-1.6MPa, which can meet the pressure requirements of most corn flake cooling processes.
- Operating Temperature: The cooler has a wide operating temperature range that can be adjusted according to the initial temperature and cooling requirements of the corn flakes. It can usually reduce the temperature of the corn flakes from a higher temperature to a suitable storage or subsequent processing temperature.
Material selection for corn flake tube cooler
- Pipe material: Stainless steel or copper pipes are usually selected, such as 304 stainless steel, 316 stainless steel, etc. These materials have good corrosion resistance, thermal conductivity and mechanical strength, which can ensure the long-term stable operation of the cooler.
- Shell and tube sheet: Generally made of carbon steel or stainless steel. Carbon steel has higher strength and lower cost, and is suitable for some occasions with low requirements for corrosion resistance; stainless steel has better corrosion resistance and hygienic properties, and is suitable for corn flake cooling systems with higher requirements for product quality.
