2. SIGNIFICANCE OF PROJECT
The problems with current techniques.
1) Cost
2) Size
3) Hygiene
4) Functionality
5) Accessibility

3. ICE AND ITS PROPERTIES
 Posses a regular crystalline structure.
 The density of ice is
0.9167 g/cm³ at 0°C.

4. • When ice melts, it absorbs as much energy as it
would take to heat an equivalent mass of water by
80 °C.
• During the melting process, the temperature
remains constant at 0 °C.
LATENT HEAT

6. DESIGN CONCEPT
 Requirement of a force to impact ice onto
blade.
 Various forces that could be used.
 Idea from the centrifuge.
 Relating it to an ice crusher for a compact
design.

8. MODEL MATERIAL

9. MATERIAL AND ITS PROPERTIES
 As material comes directly in contact with ice i.e.
water it should be corrosion resistance.
 Stainless steels are
high-alloy steels that
have superior corrosion
resistance .

10. Steel used is grade 202
austenitic steel.
 Composition
The following elements are
present in steel:
Carbon, Manganese, Silicon,
Chromium, Nickel,
Phosphorous, Sulphur,
Nitrogen.

13. Motor
 High-voltage DC brush
motor
 Operating on 100-240v
 Speed 4985 rpm

14. Specifications
 Construction permanent magnet
 Speed 4985rpm
 Output power 80W
 Voltage 100-204V
 Max. efficiency 76.2 -84%
 Max. efficiency o/p 8.6-34.3W

15. CONCLUSION
 The compact design of ice crusher gives us the
following liberties:
1) Small and easily portable
2) Doesn’t require much space
3) Consumer can enjoy clean and healthy crushed ice
for making further food products.
4) As it is used seasonally it can be accessed as and
when required.

16. Note:-
If this compact design is
considered for production
at mass level other
materials must be
considered for the basic
components.
