Continuous White Cheese Production via Centrifugal Whey Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial production of white cheese, such as paneer, faces challenges including short shelf life, texture issues due to whey pressing, time-consuming and costly salt bath processes, and batch-based operations.
Innovation Solution
A continuous process involving pasteurized milk heating, denaturation with acid or rennet, whey separation using a perforated belt, shaping with a vacuum former, and hot filling into packaging, allowing for additives incorporation and eliminating the need for a salt bath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If whey is pressed out using traditional pressing methods, then whey separation is achieved, but the texture of the white cheese deteriorates
Solution Approach 1:
The patent replaces the traditional mechanical pressing system with a centrifugal separation system. The centrifuge uses rotational force to separate whey from curd through density differences, eliminating the need for mechanical compression that damages the cheese texture. This substitution maintains effective whey removal while preserving the delicate structure of the white cheese.
2Reliability
If traditional batch production with salt bath is used, then preservation is achieved, but production time and cost increase
Solution Approach 1:
The patent implements a continuous production process where pasteurized milk is continuously heated, coagulated, separated, and formed into white cheese. The centrifugal separation and subsequent packaging occur in an uninterrupted flow, eliminating the batch-wise salt bath treatment. This continuous operation maintains preservation quality while significantly reducing production cycle time and increasing throughput.
Solution Approach 2:
The patent extracts and eliminates the time-consuming salt bath step from the traditional process. By using centrifugal separation to achieve whey removal and employing continuous processing with immediate packaging, the preservation function is maintained without requiring the intermediate salt bath treatment that delays production.
3Adaptability or versatility
If traditional batch processing is used, then production flexibility is maintained, but productivity decreases
Solution Approach 1:
The patent transforms the batch-wise production into a continuous process where milk flows continuously through heating, coagulation, centrifugal separation, and packaging stages. This continuous operation dramatically increases productivity by eliminating idle time between batches while the modular design of the centrifugal separator allows for flexible adjustment of production parameters to maintain adaptability.
