Worksite Improvement Case Studies

To steam clean the cheese adhering to pots and machines, we used a steam hose (made of rubber) with a ferrule barb hose band fastening.
This steam hose is heavy and stiff, making it difficult to use. Moreover, after about one year of use, rubber fragments appear due to inner hose deterioration. Foreign matter intrusion due to the hose fragments is a concern, and we concluded that some countermeasure needed to be done.

The rubber hose used for steam is heavy and stiff, making it very difficult for the workers responsible for washing the equipment. The rubber smell from the hose also filled the room and created an unpleasant environment.

During the flavoring filling process, a food-grade silicone hose and crimping couplings were used, but the frequent suction and pressure feed in the process meant regular hose replacement; costs mounted for crimping couplings which could not be reused.

Newly introduced production of flavorings containing large amounts of dairy components requires more stringent bacterial inspections, due to the nature of the product. The hoses are currently connected with barb fittings for hose clamp fastening, but the bumps may lead to liquid accumulation, requiring countermeasures.

Hoses are being trialled for transporting raw materials at a marine product processing plant. However, raw materials adhere to the hoses due to static electricity, and the flow rate is significantly reduced, resulting in reduced production efficiency.

For transporting raw materials at a soy sauce manufacturing plant, TOYORING-F Hose 38φ and barbed cam locks were used with hose clamp fastenings. However, during cleaning and sterilization, hot water at 80°C flows at a pressure close to the upper limit of the allowable pressure for a short time.

Hoses and cam locks are used to fasten hose bands used for transporting food products at a fermented food manufacturing plant. Leakage from the couplings. A countermeasure is needed.

TOYOSILICONE Hoses were used for conveying salad dressing and the hoses were initially cut to about 30 centimeters and fastened with clamps. But there were between 100 to 200 hoses in the plant, and they all had to be removed, washed and reattached every day. There were two problems:

(1) It took too much time
(2) The edges of the clamps were causing damage to the hoses, which had to be replaced.

A customer was cleaning hoses with a high concentration of cleaning alcohol. Because the hoses were made of PVC, the alcohol caused the hoses to become brittle, and they cracked, causing material to leak.

On a chocolate production line, a 38-millimeter PVC braided hose was in use. To comply with Public Notice No. 267 under the Ministry of Health, Labour and Welfare’s Food Sanitation Act, a replacement was needed right away. When they looked for food-grade hoses, they found a number of candidate products from other companies, but none could handle the oils and fat in chocolate.
