Food Machinery

1. 1
This assignment is designed to increase the participant's knowledge and skill in proper machine
safeguarding techniques and to highlight the benefits of guarding various types of machinery. It
is the employer's responsibility to identify and select the safeguard necessary to protect
employees and others in the work area as well as provide appropriate training in safe work
practices. Knowing when and how to properly safeguard machinery can reduce or eliminate the
potential for accidents and injuries.
Machine: Any mechanical or electrical device that transmits or modifies energy to perform any
type of work.
 Historically, a machine required to have moving parts to be classified as a machine.
 Nowadays, electronics technology has led to the development of devices without moving
parts that are often referred as machines.
Classification by working principle:
1. Mechanical components (bolts, nuts, shafts, gears, clutches, bearings etc.)
2. Non-mechanical components (electrical, optical, electronical etc.)
3. Combined components (sensors, engines, converters etc.)
Machinery:
Machinery is defined as a mechanical device or the parts that keep something working. An
example of machinery is a car's engine. An example of machinery are the people who work for a
political party; the machinery of the Republican Party.
A group of devices with moving parts that are used to perform specific jobs.

Drying Machine:
Introduction:
Vegetable drying oven adopts circulating hot air to dry vegetables. The dryer is equipped with
low noise, high temperature resistant axial flow fan and automatic temperature control system.
The whole circulation system is fully closed, most hot air circulates in the oven, having high
thermal efficiency and saving energy. The vegetable drying machine is suitable for drying
various kinds of vegetables, such as radish, potato, sweet potato, mushroom, chili, garlic, ginger,
long beans, cauliflower, bamboo fungus, bamboo shoots, etc. and the nutrition values of
vegetables can be retained after drying.

1. Utilizing forced ventilation function and adjustable air distribution plates, ensuring
temperature balance in the oven.
2. Multiple heat sources for your choice: steam, electricity, or electricity-steam dual-use.
3. Automatic constant temperature control, automatic alarm over limit, reliable operation.
4. The inner wall of the dryer machine are fully welded and adopt circular arc transition at all
transitions, no dead angle, easy to clean.
5. Unique guide rail sealing device, ensuring the sealing performance of the vegetable dryer,
helping thermal insulation and prevent pollution.
6. Adopt filters at the air inlet and outlet, ensuring cleanliness of the circulating air.
7. All the spare parts in the oven can be disassembled and assembled quickly, easy for clean and
maintenance.
8. The vegetable dryer machine is in compliance with GMP requirements.
9. Uniform trolley size and tray size. Baking tray dimensions: 640*460*45mm.
10. The oven dryer can be customized according to your requirement.

Working Principle of Hot Air Drying Oven:
Hot air circulating oven adopts steam or electricity as heat source, and axial flow fan to circulate air. After
heated by the radiator or electric heater, the hot air delivered by the circulating fan enters into the drying
room through the air duct, and transfers heat to the materials. Fresh air is replenished through the air inlet
while wet air is discharged through the air outlet. By the constant replenishing of fresh air and discharging
of wet air, the proper relative humidity in the drying oven is maintained.
Application:
1. Different types of vegetable drying.
2. Removing moisture from fruits.
3. Reducing fruits or vegetables surface area.
Frying Machine:
Introduction:
The French Fries Frying Machine adopts oil and water mixing technology which is best suitable
for frying various style French fries especially and other kinds of snack food like potato chips.
The main consistence of this fryer are oil tank, electric cabinet, fan, water drainage valve, oil
drainage valve, natural wind cooling mouth and some other components, these parts work
independently and finish the frying process together very efficiently.

4. 4
Advantages of Frying Machine:
1. Advance oil and water mixing technology taking features of different density of oil and water,
the oil is in upper for frying food and water is at the bottom for absorbing the residues which are
from the frying food.
2. 50% Oil saving. The oil can be made most use, because the oil residues can be drained with
water though the water drainage valve.
3. The machine is equipped with automatic discharging device, which can make you
automatically operation and save the labor cost.
4. Easy to operate. The automatically bimetallic temperature controllers include oil temperature
controller and water temperature controller, which give you an easy operation choice. 5. 40%
energy saving. The advanced and efficient heating system avoids energy loss and save your
energy expenditure cost.
6. The stainless steel manufacture guarantees a longer service life and high sanitary condition.
Working principle of oil& water frying machine:
The temperature of oil and water can be set and controlled in a certain range by the natural wind
cooling system and the automatic cold water cycling system so that the water will not boil and
spill in the oil. The waste and residue produced during frying will deposit in the water and
discharge out of the machine once the operation finishes so that the frying oil keeps clean and
fresh without turning dark at all.
Application:
1. Semi fried chips can produce.
2. Different types of potato chips production.
3. Larger production quantities.

Cutting Machine:
Introduction:
Cutting machine can cut potato and other root vegetables and fruits into slices, crinkled slice,
strips and shreds, the thickness can be adjusted by increasing or decreasing spacers, having wide
applications and multiple functions. It is a necessary machine for potato chips and french fries
production, and an ideal choice for fruits and vegetables processing.
Fig: cutting machine.
Working principle of Cutting Machine:
Before operating the potato slicer machine, decide whether to cut slices or strips. If you need
slices, take out the strip-cutting knife box and fix the spare board to where the strip-cutting knife
was. Turn on the power switch and put the clean and peeled potatoes consecutively into the feed
inlet. Then the potato slices will come out from the outlet of the potato slicing machine. During
cutting, add a little water into the outlet of the slicer machine, you will get better end products.
