Industrial dryers and hot air dryers, differences and applications in fact

Why do we need to distinguish between industrial dryers and residential dryers when choosing a dryer to use, ensuring it meets product drying requirements? Because it is also a way for manufacturers to understand the overview of drying equipment currently on the market today, and once you have a clear understanding, dividing group names like this is no longer necessary.

Basically, industrial dryers are general drying equipment used in industrial companies, as the image above was taken at the Vietnam LS system and electric cable company. Or many other industrial companies. You can see them in the Reference section on this website. This is a group of high-temperature dryers with a commonly used drying temperature range of 35 ~ 160^oC and even higher up to 300^oC depending on the purpose of use of each customer. However, with the current widespread demand, the models This dryer is also used by many people, not only for people’s homes, small establishments, small manufacturing shops,… as long as it meets the correct requirements.

So, whether we need to distinguish industrial dryers from residential dryers or not is no longer important. The important thing is that you need to find out and come up with 3 main factors, including the drying temperature range needed, the size of the inside of the machine or the drying volume per time and the drying type. I will analyze the 3 factors above to help you understand this content.

The 3 factors above to help you understand this content:

1. Drying temperature range: we often search with specific keywords like dried shrimp dryer, dried fruit dryer, dried fish dryer, dried meat dryer… that is, search with the name of the dryer and the name of the drying product. Therefore, searchers will easily be confused and difficult to understand… The key issue in this section is the drying temperature range to use. For example, dried fruit products, dried fish, dried beef, dried herbs, dried grains (not cooked)…, the drying temperature range only needs to be used at 35 ~ 95^oC, these are hot air dryers with the principle of circulating hot drying, suitable for drying many common products. If you need to dry crispy grains, choosing a higher drying temperature range, 35 ~ 160^oC, is appropriate.
2. Size of the inside of the drying chamber or drying volume per time: this is important information for us to advise on the appropriate size dryer for the user. Depending on the specific drying product, we need different information, for example, you want to dry dried shrimp, dried fish… with a drying volume of 20kg, 50kg or 100kg/batch, it is very easy to choose the machine, with industry drying for components, machine parts… cannot be calculated in kg, it will be calculated by the required size of the drying chamber.
3. Drying principle: for industrial dryers and hot air dryers, the drying principle is the same, both are circulating heating with hot wind blowing continuously in the drying chamber to evaporate water in the product. When talking about current drying principles, there are 3 common types of drying, 1 is hot circulation drying, 2 is heat pump drying with dry air (You can see the website maysaylanh.com) and 3 is the principle of sublimation drying at negative cold temperature in the vacuum drying chamber, please see the freeze dryer website to understand clearly.

So with the 3 basic bullet points above will help you find the right dryer for the product without having to differentiate between industrial dryers and hot air dryers to make it complicated.
