In recent years, the rapid development of the pharmaceutical industry has led to the gradual expansion of the related pharmaceutical equipment market. At the same time, tunnel ovens have become a new choice for drying materials in the pharmaceutical industry and other industries. Keywords such as "energy saving", "environmental protection" and "high efficiency" have covered almost all industries, which in turn has prompted industrial equipment manufacturers to continuously innovate and improve their equipment to meet the market's higher The tunnel oven is constantly upgrading and evolving to meet these requirements and goals.
What Is Tunnel Oven
Characteristics of tunnel oven:
The heating element of the tunnel oven is installed at the top of the oven to improve the thermal efficiency. Oven equipped with electrical control cabinet, temperature digital display control. Can control any constant temperature state. The outlet can be purified by vertical laminar flow with grade 100 cleanliness to cool the material so that the material is in a strict aseptic and dust-free state. Aluminum silicate is used as insulation material in the oven insulation layer, which has good insulation performance.
In the field of sterilization, tunnel sterilization oven is widely used in the pharmaceutical production of various ampule bottles, easy to pull bottles, penicillin bottles and other glass containers of drying, sterilization, can also be used for chemical, food, electronic industries and other industrial sectors of the material drying. Tunnel sterilization oven continuous optimization and improvement of design, in the sterilization drying equipment market advantages prominent.
Tunnel oven is mainly divided into four parts, feeding area, drying area, discharging area and the conveying line part:
- Feeding area:
Before the product enters the drying area, the place where the product is placed, its length is about 500 mm-1000 mm. Products through the tunnel oven feeding area automatically into the second part of the drying area for heating, drying and other heat treatment operations.
- Drying area:
It is mainly composed of four parts: frame, blower motor, heating pipe and box body. The two layers between the box body filled with thermal insulation material. It can bake continuously and uninterruptedly to improve product production efficiency. Multi-segment independent PID temperature control, uniform temperature in the oven. The speed of conveying line is frequency-controlled, freely adjustable, smooth running and high production efficiency.
- Discharge area:
Cooling fan can be added as needed to accelerate the cooling of the products in the drying area for the next process.
- The conveying line part:
Mesh belt and plate chain conveying line are equipped with transmission chains on both sides to solve the phenomenon of running off during transportation. Tunnel oven is segmented heating, independent electric box control, easy to operate. The structure is mainly composed of two major parts: conveying system and drying oven.
Difference With Other Ovens
As advanced versions of the ordinary drying oven, vacuum oven and tunnel oven are often compared together.
Tunnel oven is generally dried by heating, there is no vacuum drying, like the assembly line, generally can work continuously.
Vacuum ovens are generally dried by vacuum and heating. They are distributed. One batch of drying products is taken out, and then another batch is dried.
Vacuum oven is in baking at the same time to vacuum the container, the most important feature is to speed up the drying of non-oil liquids, such as water, volatile solvents and so on. As LS said, the vacuum oven has the process of pumping air and breaking the air, not continuous.
The two sides of the tunnel sterilization oven are equipped with a chain drive, which can solve the phenomenon of deviation in the transportation process; Oven segment heating, independent electric box control, easy to operate.
From the structure point of view, it is mainly composed of conveyor system and drying furnace two parts. Multi-stage independent PID temperature control, uniform temperature in the furnace. At the same time, the transmission speed can be frequency control, adjust freely, smooth operation, high production efficiency.
With the tunnel sterilization oven application field gradually widened, in order to meet the product needs of different customers, the tunnel oven transmission on the market today mainly uses stainless steel chain or stainless steel mesh belt, for different product production, users can adjust the appropriate speed according to different requirements.
In the past, the cooling section of the tunnel oven generally required measures to reduce the risk after cleaning, as the cooling section was not sterile after restarting, but generally sterilized. And now the tunnel oven net belt after production can realize online cleaning, sterilization and other functions, and the cooling section in A laminar flow protection.
Advantages of tunnel ovens
Tunnel ovens are used widely in the food processing industry for baking and drying products. There are certain differences between tunnel ovens and other ovens that make them stand out. Firstly, tunnel ovens are designed to operate continuously, unlike batch ovens that operate intermittently, thus making them more efficient in terms of energy use and product output.
Secondly, tunnel ovens employ a conveyor system to transport products through the oven, resulting in a higher production rate and consistency in quality, as the products are baked evenly. Furthermore, tunnel ovens are versatile and can be designed to suit different processing needs, such as for baking bread, pizzas, or drying fruits and vegetables.
Tunnel ovens offer several unique advantages that make them the preferred choice for many food processors. As mentioned earlier, their continuous operating capability helps to save energy and increase production output. They also offer precise controls over temperature, airflow, and humidity, providing consistent and even baking or drying of products.
Moreover, tunnel ovens have a smaller footprint than batch ovens, which is particularly beneficial for processors with limited space. Finally, tunnel ovens are customizable and can be designed to meet specific processing needs. This makes them an ideal choice for food processing companies looking to improve their operations and product quality.
In conclusion, tunnel ovens stand out for their operational efficiency, consistent product quality, versatility, and customization options. They are a reliable solution for food processors who want reliable and efficient baking or drying equipment to meet their production needs.
