Abstract
The disclosed method and apparatus for crushing material such as ice include a controller to actively control the speed, volume, temperature, and humidity of airflow to improve the crushing efficiency.
Claims16
A method of independently controlling a predetermined aspect of material crushing operation, comprising the steps of:
- rotating crushing blades in a covered chamber;
- inputting material to be crushed towards the covered chamber through at least a first inlet;
- crushing the material;
- inputting airflow into the covered chamber through at least a second inlet while the material is being crushed;
- independently controlling speed and volume of the airflow through the second inlet independent of the material input through the first inlet;
- and
- outputting the crushed material through an outlet from the covered chamber.
4 more elements
An apparatus for crushing material, comprising:
- crushing blades rotatably positioned in a housing for crushing a predetermined material;
- at least a first inlet located on the housing for allowing the material to be deposited into the housing;
- at least a second inlet also located on the housing for inputting airflow into the housing at a predetermined angle while the material is being crushed;
- an outlet for outputting the crushed material from the housing;
- and
- a controller connected to said second inlet for independently controlling speed and volume of the airflow through the second inlet independent of the material input through the first inlet.
3 more elements
An apparatus for crushing material, comprising:
- crushing blades rotatably positioned in a housing for crushing a predetermined material;
- an outlet located on the housing for outputting the crushed material from the housing;
- at least an inlet located on the housing near and above said outlet for allowing the material to be deposited into the housing and for inputting airflow into the housing;
- and
- a controller connected to said inlet for controlling speed and volume of the airflow.
