Case Study 1: Raw Material Supply Plant for a Large Coffee Chain Brand
– Before use: Green coffee beans were manually transported to a temporary storage area next to the roasting equipment, resulting in high labour intensity, low efficiency, a daily processing capacity of only 5 tonnes, and a high risk of contamination.
– Results after installing the vacuum conveying system: A customised vacuum conveying system was installed, with pipe diameters tailored to the size of the green beans and precise suction force adjustment. Daily processing capacity increased to 15 tonnes, with the number of workers reduced from 8 to 2 (responsible only for equipment monitoring and maintenance). The probability of contamination dropped from approximately 5% to nearly 0%, resulting in a significant reduction in raw material loss costs due to contamination.
Case Study Company 2: Instant Coffee Manufacturer
– Pre-implementation situation: Coffee powder was transported using a screw conveyor, which was prone to residue buildup and difficult to clean, leading to inconsistent taste between batches, high risk of foreign object contamination, and a consumer complaint rate of 2%.
– Results after using the vacuum conveying system: A vacuum conveying system made of food-grade stainless steel was adopted, equipped with an automatic reverse-blow cleaning system and high-precision filtration devices. Taste differences between batches are now imperceptible to the naked eye, foreign object contamination rates have dropped to 0.01%, consumer complaint rates have significantly decreased, and product market reputation has improved.
Case Study 3: Coffee Capsule Manufacturing Company
– Pre-implementation situation: Traditional gravity-fed coffee powder filling into capsules resulted in significant filling quantity errors, leading to unstable coffee concentration, an 8% defect rate, and severe dust accumulation in the workshop.
– Effects after using a vacuum conveying system: By introducing a vacuum conveying system combined with high-precision metering devices, coffee powder filling volume errors were controlled within ±0.5 grams, the defect rate was reduced to 2%, and dust concentration in the workshop decreased by 80%, improving the working environment and enhancing production safety.
