Q 1. What is the Difference Between Oven and the Furnace?
Ans. sOven is described as an enclosed chamber having the interior of the metal and another section that produces heat.

Furnace too is an enclosed heat in which heat is produced for an oven, to destroy refuse, to smelt or refine ores. The furnaces can produce more intense heat and are consist of interior lining of refractory material.

Q 2. What should be the Major Considerations while buying ovens?
Ans. Heating, Ventilation and Insulation Systems should be thorougly checked before buying the Ovens.

Q 3. What is Oven Drying?
Ans. This is a process in which liquid is evaporated from a mixture of liquids and solids using a forced convection oven chamber in order to supply the heat of vaporization, local velocity and removal of the heated mixture of process air and vapor without disturbing the wetted solids.

Q 4. What is difference between Batch Oven and Continuous Ovens?
Ans. Batch ovens are those ovens that are used for containing discrete quantity of material per processing operation. The processing in these ovens take place in three phases. Warming to temperature, soaking at temperature, cooling to ambient temperature. Using same physical space each phase is conducted in sequence.

Continuous Ovens are designed to process multiple batches in sequence without interruption. A continuous oven may provide for uninterrupted materials flow through several phases depending upon the materials to be processed. The process includes warming to temperature, soaking at one or more different temperatures and cooling to ambient temperature.

Q 5. Please give some informations about Semi continuous Ovens?
Ans. Semi-continuous oven is a single oven fabricated for the processing of multiple batches sequentially in a single zone or work space. The oven combines both the processing phases that is warming and soaking into a single zone or chamber and normally provides for external product cooling.

Q 6. What are the Major Sub Systems of the Ovens?
Ans. The major sub system of the ovens are:

Shell
Shell is an envelope of the oven which is insulated. Other systems are located inside the ovens like workspace, heater, air impeller, duct and other systems.

Duct
It constitutes the conduct through which the air is delivered to and removed from the work space of the oven.

Circulation
Circulation moves the air through the heater, duct system and the workspace.

Ventilation
Through ventilation system air is either added or it is subtracted from, the oven chamber.

Heating
Heating system is used for the conversion of energy to heat the circulating air which warms the contents of the workspace.
