*''' Heat up Zone'''
The oven tunnel is divided into various subsections, the oven zones. The heat-up zone described here, is such a oven zone.
It is a convection zone. The car body or the dried material is convectively heated in the oven's convection zone by hot air (recirculation air) directly streaming along the car body.
The air flows from the side recirculation air pressure ducts and is blown through air filters onto the car body by nozzles.
Each of the oven's convection zones has its own recirculation air heater unit (convection hot box) with which the temperature in the respective zone is controlled. In the oven's convection zone the energy for heating the car body is transferred by hot air flowing directly pass the car body. To this end the air is heated in the heat exchanger of the recirculation air heater unit and is then fed via feed ducts in the oven. This air distribution ducts are designed as a longitudinal pressure ducts on each side of the oven zone.
From the air distribution plenum, air flows via compact high-temperature filters into the filter boxes arranged the length of the plenum and is then blown through duct wall-mounted nozzles onto the car body inside the oven.
The air is sucked back into the heat exchanger of the recirculation air heater unit through intake openings on both sides of the floor. The air is moved in a cycle from the recirculation air heater unit to the oven, from the oven back to the recirculation air heater unit and back to the oven, etc. For this reason the air is called recirculation air.
Industrial convection oven used in the manufacture of aircraft components. Heating is by gas-fired heat exchanger; fully automated control system holds air temperature within 2°F.Industrial "Zanolli" double hearth deck oven (left) and "Sveba-Dahlen" rotary rack oven (right) at the Faculty of Food Technology, Latvia University of Agriculture bakery
Industrial ovens are heated chambers used for a variety of industrial applications, including drying, curing, or baking components, parts or final products. Industrial ovens can be used for large or small volume applications, in batches or continuously with a conveyor line, and a variety of temperature ranges, sizes and configurations.
Such ovens are used in many different applications, including chemical processing, food production, and even in the electronics industry, where circuit boards are run through a conveyor oven to attach surface mount components.
Some common types of industrial ovens include:
Curing ovens – Designed to cause a chemical reaction in a substance once a specific temperature is reached. Powder coating is one common curing oven use.
Drying ovens – Designed to remove moisture. Typical applications are pre-treating and painting. Such ovens are also sometimes known as kilns, though they do not reach the same high temperatures as are used in ceramic kilns.
Baking ovens – Combines the function of curing and drying ovens.
Reflow Ovens – A reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCB). A graphical example of a convection reflow oven. The oven contains multiple zones, which can be individually controlled for temperature. Generally there are several heating zones followed by one or more cooling zones. The PCB moves through the oven on a conveyor belt, and is therefore subjected to a controlled time-temperature profile. Convection Reflow Oven Detailed Description
Batch ovens – Also called cabinet or Walk-in/Truck-in ovens, batch ovens allow for curing, drying or baking in small batches using wheeled racks, carts or trucks. Ovens such as this are often found in large-volume bakeries in places such as supermarkets.
Conveyor or Continuous Ovens – Typically part of an automated conveyor processing line, conveyor ovens allow for higher volume processing.
