στην πραγματικότητα, 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. Σαν άποτέλεσμα, the people outside are too hot. But the temperature of the pizza in the oven does not meet the requirements. Εξάλλου, 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
(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, και τα λοιπά.
Επιπροσθέτως, 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 Secondly, 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. Για παράδειγμα, for conveyor pizza oven, it also uses the stainless steel mesh belt. Φυσικά, 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. Επιπλέον, 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 Thirdly, conveyor dryer heating elements to choose
For industrial conveyor ovens, there are several heaters available. Ανάμεσα τους, 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. Ωστόσο, 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. Την ίδια στιγμή, metal heat sinks are wound on the surface. So conveyor dryer with this heater has faster heating speed and thermal efficiency.
7. Συχνές ερωτήσεις
Q1: how long does it take to cook a pizza in a conveyor oven?
Α1: Για παράδειγμα, for American pancake pizza, it usually takes 4 to 5 λεπτά. The temperature is mostly 230°C.
Q2: how much is a conveyor pizza oven?
Α2: 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.
