5. Vergelyking van verskeie tonnel vervoer oonde

Understanding the characteristics of different baking equipment will help us make better choices. Volgende, we will introduce the comparison of drying ovens.

(1) pizza conveyor oven vs deck oven

For deck oven: This type of oven is the most common. Many pizzerias use deck oven. This kind of oven uses the upper and lower fire to heat up. It takes a long time to bake. Daarbenewens, you need to flip the pizza constantly.

Pizza baked in a deck oven has a lot of moisture. It is easy to cause the pizza bottom to separate from the cheese. Especially for fruits or ingredients with high water content. This kind of oven is easy to dry and burn the pizza. Buitendien, the heating is uneven. So it will affect the taste. Natuurlik, deck oven is cheaper than conveyor toaster oven.

For conveyor pizza oven: It uses high temperature pressure jet baking technology. The hot air quickly penetrates the inside of the pizza. So it makes the heating more even and the taste is better. Daarbenewens, you can easily adjust the temperature and time of pizza tunnel oven according to your own needs.

During the baking process, no need human intervention. We just need to wait for the pizza to come out from conveyor pizza oven belt. The whole process is simple and efficient, tyd en moeite bespaar.

(2) conveyor dryer vs drying oven

For drying oven: it usually means the industrial vertical dryer. The product placement method is generally tray push or push rack push. Drying oven occupies a small area. Compared with the tunnel conveyor dryer, the price is relatively cheaper. But the production capacity is small. Daarbenewens, it requires manual loading and unloading.

For conveyor dryer: Continuous tunnel furnace has higher price. And it occupies large area. But tunnel dryer is efficient. Daarom, it is particularly suitable for mass drying operations. The tunnel furnace adds a baking furnace cover on the basis of the conveyor production line. The product enters the conveyor oven from one end trough the oven belt. Na droog, it moves out from another end. Daarom, it requires no manual handling. So save time.

(3) infrared conveyor oven vs microwave tunnel dryer

For IR conveyor dryer: Infrared heating uses the principle of electromagnetic radiation heat transfer. It transfers heat in a direct way to achieve the purpose of drying objects. Infrared has a shorter wavelength than microwaves, so its energy is higher than microwaves. IR heating is from the outside to the inside. Firstly ir conveyor oven heat object surface. Then the temperature rises, thereby evaporating water.

In terms of application, infrared tunnel furnaces are more commonly used in industrial fields. Although it can also dry food, it has no sterilization function.

For microwave tunnel dryer: Because the vibration frequency of the microwave and water molecules is close, it is conducive to the formation of resonance. So it allows the food to heat up evenly from the inside. Daarbenewens, microwave conveyor dryer has sterilization function.

6. Hoe om die regte tonnel vervoer oond droog te kies?

When buying drying equipment, you need to pay attention to various details. Only so we can choose a good conveyor dryer. In addition to clarifying the basic dimensions and parameters of the oven, it needs to confirm the following key points.

(1) Choose conveyor pizza oven

Soos bogenoem, although the deck oven is cheaper, the pizza made by conveyor oven tastes better. So if you’re pizza shop, it’d better to choose commercial conveyor pizza oven.

① gas or electric conveyor pizza oven?

In werklikheid, the taste is similar. Compared with an electric oven, the cost of a gas pizza oven is lower. The operating cost of an electric pizza oven is directly proportional to the volume. The larger the volume, the greater the power. Then it costs more electricity.

② choose the heating type

The heating method will affect the taste of the pizza. Some pizza conveyors are similar in appearance. But it uses is vertical heating. The fan is on the side. When opening belt oven, the fan blows out the heat in the oven. As gevolg daarvan, the people outside are too hot. But the temperature of the pizza in the oven does not meet the requirements. Daarbenewens, the heating is uneven. The pizza is not only bad in appearance, but also bad in taste.

So we must communicate well with the manufacturers. Make sure that the pizza oven uses hot air jet technology. Because only with this baking technique, the pizza tastes better.

③ Thermal insulation effect

Some pizza ovens are not thick enough for insulation cotton. Op dieselfde tyd, cooling measures have not been taken. It causes the surface of the device to become hot. Buitendien, the pizza cooker feels very hot. Daarom, we must confirm the thermal insulation effect of pizza conveyor dryer.

(2) Choose industrial continuous conveyor tunnel dryer

Tunnel furnaces have a wide range of applications. When purchasing, it is very important to confirm the technical details.

① First of all, inform the product application information

The customer needs to inform the relevant information of the products for drying, such as product size, baking process requirements. Is it necessary to bake moisture or to bake its paint or flux, ens.

Daarbenewens, what is the baking temperature range? Is there a temperature difference requirement? How about the heating time? And how long does it take to reach the drying temperature?

② Tweedens, confirm the materials & types of conveyor dryer parts

For inner plate material: when working temperature less than 300℃, it can choose the cheaper galvanized sheet. If it is greater than 300°C, stainless steel should be used. Sometimes in order to prevent material deformation, it is necessary to increase the frame.

For conveyor belt: different applications, different conveyor oven belts to choose. For conveyor dryer screen printing, we usually choose the Teflon mesh belt. Because the temp. is not high in printing industry, the Teflon belt can bear 0~250℃. If tunnel dryer temperature is higher, we need to use stainless steel mesh belt. Byvoorbeeld, for conveyor pizza oven, it also uses the stainless steel mesh belt. Natuurlik, all of them use the conveyor belt as a direct conveying carrier.

If you need use the tray as conveying carrier, it can choose the roller conveyor or slat chain conveyor. Daarbenewens, if the baking temperature is not higher than 80°C, it can also use PVC or PU belts. In the electronics industry, we usually choose belt conveyor dryer.

③ Derdens, conveyor dryer heating elements to choose

For industrial conveyor ovens, there are several heaters available. Tussen hulle, the transparent quartz tube and black ceramic tube use the infrared heating principle. Quartz heater has very wide applications. But it’s fragile during transportation.

The second is stainless steel heating tube. It is an electric heating element with a metal shell. It is sturdy and durable. Egter, the heating time is not as fast as other heating tubes.

The third type is the w-shaped heating tube commonly used in tunnel dryers. It uses a metal tube as its outer shell. Electric heating alloy wires are evenly distributed inner the tube. Op dieselfde tyd, metal heat sinks are wound on the surface. So conveyor dryer with this heater has faster heating speed and thermal efficiency.

7. Vrae

V1: how long does it take to cook a pizza in a conveyor oven?

A1: Byvoorbeeld, for American pancake pizza, it usually takes 4 aan 5 minute. The temperature is mostly 230°C.

V2: how much is a conveyor pizza oven?

A2: Belt ovens with hot air jet technology are more expensive than those without. The former often cost several thousand dollars. But the latter only costs a few hundred dollars.

V3: Wat is die verskil tussen skinkborddroër en tonneldroër?
A3: They tray dryer is suitable for small batch baking. Besides it doesn’t take up space. The tunnel furnace is suitable for mass drying. Daarbenewens, you can connect conveyor dryer to other production lines.
