KRUSA crusher efficiently breaks olives into paste with customizable sieve and blade options—maximizing oil yield and phenolic content without overheating the cells.
BSTM manufactures the following crushers tailored to different needs:
- Knife Crusher- Crusher with Pit Separator
Different sieve options are available for various olive varieties and harvest periods (early, mid, and late):
- 5 mm
- 6 mm
- 7 mm
Application
Paste preparation is a critical stage that directly affects both the quality and yield of olive oil. Breaking the olive cell membranes without generating excess heat has a significant impact on the aroma and polyphenol content of the oil. This is also when enzymatic activity, particularly involving lipoxygenase (LOX), begins.
Benefits
- High yield- High phenolic compound retention- High aroma efficiency- Optimal operating temperatures- Sieve options for different olive types- Interchangeable hammer / knife / pin crushing heads
Design
BSTM crushers and pit separators are designed in a modular structure on a single chassis. This modularity allows users to switch between different crushing technologies based on the olive type, making it possible to prepare the most suitable paste.
The unit includes three motors:
- One motor for the crushing mechanism- One motor for the scraper mechanism- One motor (with adjustable speed) for feeding the crusher
Thanks to the easily interchangeable hammer, knife, and pin heads, along with various sieve options, the unit offers flexibility for different olive varieties and harvest stages.
Working Principles
Crushing Unit: Olives are fed into the crusher via a screw conveyor. Rotating blades break the olives and push the paste through the fixed sieve holes using a hammer mechanism. The thickness and texture of the resulting paste can be adjusted using different sieve sizes.
Cooling System: BSTM’s specially designed cooling system allows users to control the desired temperature during crushing. Since temperature is a key factor affecting olive oil quality, this system gives the operator full control over processing conditions.
