Principle The use of moist heat facilitates the killing of all microorganisms including heat resistant endospores which is achieved by heating the materials inside the device at temperatures above the boiling point of water According to the principle of gas laws this can be achieved by raising the pressure inside the The boiling point vapor pressure equals that of the
The main two compartments of the vapor absorption chiller are Low pressure side; High pressure side; These two main components are subdivided into again two parts as below #1 Low pressure side 1 Evaporator 2 Absorber #2 High pressure side 1 Generator 2 Condenser Working material in vapor absorption chiller Refrigerant DM Water
Working Principle of Jigger Dyeing Machine The jigger machines have two main rollers which revolve on smooth bearings and are attached to with a suitable driving mechanism which can be reversed when required The fabric is wound on one of the main rollers and fed from the other The fabric move from one roller to the other through the dye
4 Figure 1 Freeze Dryer Working Principle of Freeze Dryer Freeze drying is also called as lyophilization It is the removal of water in the form of vapour directly from the frozen state ice without changing into the liquid state
Working principle Let us now understand how a screening machine works A screening machine has an inbuilt drive that induces vibration and a screen media that helps in particle separation
Belt dryer machine is a continuous dryer with large scale and efficient drying effect It can be used for drying fruits vegetables or seafood Working principle of the continuous conveyor dryer continuous conveyor dryer video The main principle is spreading the material on the net belt through the conveyor dragging the transmission
The principle of Tablet Compression Machine The basic principle behind the tablet compression machine is hydraulic pressure This pressure is transmitted unreduced through the static fluid Any externally applied pressure is transmitted via static fluid to all the directions in the same proportion
Rotary dryers find applications in a wide range of industries including agriculture mining pharmaceuticals chemicals and more Some common applications include Drying Agricultural Products Rotary dryers are used in the agricultural industry to dry crops such as grains corn and rice before storage or further processing
The main objectives of drying include to preserve foods and increase their shelf life by reducing the water content and water activity; avoid the need for use of refrigeration systems The basic working principle of this incredible machine is the continuous circulation of hot air In the tray dryer moisture is removed from the solids that
The principle of Working In rapid mixer granulator the formation of granules occurs by rising whirling and tumbling motion of the material Dry mixing takes about 3 5 minutes to mix the ingredients wet mixing takes 5 10 minutes to make the wet mass of material while the granulation process takes 5 10 minutes to make mm to mm
The main working principle of the organic dry covering method is to use the organic carbon in organic materials such as soil sludge municipal waste compost and sawdust to consume oxygen during the decomposition process thereby indirectly reducing the oxygen content entering the sulfide minerals [50] as shown in Fig 4 b
3 Working Principle of Vacuum Dryer Vacuum Dryer involves the indirect application of heat or steam to the material tinder evacuated conditions vacuum is created inside the dryer Under such conditions the moisture evaporates at a temperature lower than its boiling point
Temperature and relative humidity of the drying air • Seeds max 43°C • Fist stage drying max 120°C • Second stage drying max 55°C Air velocity • Too low > air is saturated before leaving the dryer • Too highToo high > faster drying but wast of energyfaster drying but wast of energy • Low temperature drying m/s
The third type of classification used in mining is the Hydrocyclone commonly called a Cyclone Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment a pump To understand the Hydrocyclone Working Principle we must first know its components Beginning at the top there is the OVERFLOW DISCHARGE
3 Efficiency The drying principle of absorbent materials centrifugal drying principle and hot air drying principle are used to make the rain attached to the umbrella rain dry quickly and the water droplets on the umbrella cloth are thrown off under the action of centrifugal force and fall into the rainwater collection box [8]
Induction Heating Working Principle and Applications Induction heating is the process of heating the materials which are electrically conductive by electromagnetic induction like Principle of Induction HeatingInduction heating makes use of the induced current by the electromagnetic induction in the charge to be heated The induction hea
Spray drying is a technique based on the transformation of a fluid into a dry powder by atomization in a hot drying gas stream that is generally air [1] The spray drying process consists of four fundamental steps i atomization of the liquid feed ii drying of spray into drying gas iii formation of dry particles and iv separation and collection of the dry product from the
Principles of Freeze Drying The freeze drying process consists of three stages prefreezing primary drying and secondary drying Prefreezing Since freeze drying is a change in state from the solid phase to the gaseous phase material to be freeze dried must first be adequately prefrozen The method of prefreezing and the final temperature of the
That means a lyophilizer will have systems of refrigeration vacuum heating drying chamber vapor collect condenser and controller as well as the auxiliary components like temperature probes vacuum sensors software and so on Working Principle of Lyophilization Lyophilization is based on a simple principle of physics called
Working Principle of Drilling Machines The working principle of any drilling machine remains almost similar When power is supplied to the motor the spindle rotates causing the attached stepped pulley to also rotate as shown in the image below Fig 1 Working of a Drilling Machine
The Working Principle of Freeze drying Freeze drying is carried out using the principle of sublimation drying technique the material to be dried is frozen rapidly at low temperature and then under the appropriate vacuum so that the sublimation of frozen water molecules directly into a steam escape process Frozen the product was dried
