Snack hydraulic press

Edible Protein Ingredients. As of the mid-1990s only peanuts and soybeans are converted iato proteia iagredients for use ia food products. Peanuts are hydraulically pressed to remove about 55% of the oil and the pressed peanuts are then ground iato flours and sold raw or roasted for use ia baked products, snacks, and confections. 

The hydraulic or Carver press is commonly used to determine oil for quick quality control purposes. A ground sample is placed in a chamber for mechanical-pressing extraction. After the pressing cycle is completed, the free oil or the partially defatted snack sample is weighed. The instrument should be calibrated for each type of snack because each type leaves different amounts of residual oil (around 12% oil). Values should be correlated with solvent extraction values.
