Hot Sale Conveyor Oven Industrial Tunnel Drying Oven
Product Description
Tunnel oven/conveyor oven
Electrically heated tunnel oven
GRANDE electric heated tunnel ovens are based on a mature and time-tested system with a 10 year proven record of reliable round the clock production.The design is flexible and energy efficient and is built for decades of continuous use.The ovens are suitable for variety of products,ranging from buns to bread,cakes,moon-cakes and pastries.The tunnel ovens are manufactured in two basic versions,depending on the desired temperature range:Normal temperature up to 250ºC(482ºF ) or high temperature up to 500ºC(935ºF ).
Features & Benefits
Energy saving technology
GRANDE tunnel ovens are built with super insulating material that ensures that very limited heat escapes from the ovens resulting in the exterior being relatively cool.The exterior is made of stainless steel and our ovens are known throughout the world of their advance technology and energy efficiency.
Heating
The tunnel ovens are heated by the tube elements with double heating spirals.They are specially made for each oven to maximize the heat control and reliability of the elements.On average,we use 12 elements per meter of oven.The elements,placed on the top of the oven chamber and below the belt,are easily accessed from the side.
Turbo Zone
From some products,especially when baking with tins,the use of air circulation from turbo fans in combination with radiant heat is suitable.In such cases the oven is equipped with turbo zones.In a mesh belt oven,the hot air is forced through the belt and in a solid steel belt oven the hot air is blown horizontally along the zone.Turbo zones allow for the baking time to be reduced and lower temperatures used.With the adjustable fan speed the optimal turbo effect can be reached.
Steam system
In ovens equipped with a steam system the first part of the oven contains steam spread boxes made out of the highest grade of stainless steel.Valves with indicators are used to adjust the proper flow of steam.
Oven Control System
The PLC touchscreen is designed to be easy to use and give the best possible overview and control.Apart from temperature regulation and oven control,the touchscreen also comes standard with recipe handling,alarms,log function and Internet connectivity.
Belt Driving System
A frequency converter controls the speed of the driver motor,and the robust belt driving system provides optimal reliability and exact baking time.Long ovens and ovens for heavy products are fitted with double drive system,each with its own motor.
Belt conveyor ovens
The lowest cost and most common type of conveyor oven,belt conveyor ovens are extremely versatile and best suited for relatively light loads.In addition to standard wire mesh belts, coated fiberglass reinforced belts are also available for temperatures up to 500ºC(935ºF ).These belts are non-marring and therefore well suited for handling coatings or finished products.
Chain & Slat conveyor ovens
These conveyor ovens are best suited for medium size loads or products with inconsistent conveying surfaces.Chain conveyors are available in two or three strand configurations.A plate "Slat" can be attached to two chain strands,which provides a flat surface for the products or a means to mount fixtures required to support the products through the oven.
Roller conveyor ovens
Also know as roller hearth ovens,theses ovens have the highest conveyor load capacity.A series of rollers,mounted in bearings with sprockets on one end are driven by a common drive chain(or series of chain loops) connected to a gear motor.This conveyor design is also suited for Zer-pressure zoned accumulation,allowing products to accumulate inside the oven,independent of the rate of discharge.

Grande offers two types of standard models: the space-saving vertical ovens and the horizontal ovens. Both provide horizontal airflow for even exposure to all samples. Control constancy as low as ±0.1°C and uniformity as low as ±0.5°C ensures accurate operation. An exhaust damper is included to ventilate the oven and allow quick cool-down.
The standard controller offers two-step programming for simple heat-up or shut-down steps. An inexpensive upgrade allows creation of up to ten programs for full cycling applications. The large display is easy to use and read. Four levels of overheat protection are included for safety. A wide variety of options are also available.
