Hot joint is recommended. Delicate fabric material is used, and unprocessed belt edge and cold joint may result in unstable joint strength. and reduces the risk of foreign matter inclusion.
Suppresses belt edge fraying without additional processing,
Contributes to belt sanitation by restraining bacterial reproduction and mold generation
Test sample: Coliform bacteria
Viable cell count immediately after inoculation: 250,000
After 24 hours at 35℃: 10 or less
Antifungal test in compliance with JIS Z2911 (5 types of fungi)
After 28 days from cultivation: up to 25% less cultivation overall
- Unpackaged food conveyance
A “O” in tables for F. M and S Series indicates that the belts meet Article 370 standards of the Food Sanitation Act of the Ministry of health and welfare. Please do not use other belts for unpackaged food other than those marked “O” other belts maybe used to convey foods packaged in boxes, trays, etc.
- Ministry of Health, Labor and Welfare Food hygiene Bulletin No. 370
This standard addresses food additives and related topics, which it categorizes as (1) food products, (2)additives, (3) tools and packaging containers, (4) toys, and (5) cleaning agents. Synthetic resin tools and packaging containers are subject to the general standard as well as individual standards that have been formulated for each resin material. Manufacturers must carry out predetermined hygienic tests (material tests and elution tests) using the ﬁnal product and obtain passing results.
- FDA (Federal Food, Drug, and Cosmetic Act: FFDCA)
This regulation governs tools and packaging containers for food products in the U.S. Indirect food additives are governed by 21 CFR §174 to §186 (Code of Federal Regulations). Materials with which foods make contact as listed in 21 CFR are regulated on the basis of individual materials, products, and applications, and their safety is subject to approval by the FDA.
- PIM (Plastic Implementation Measure): Regulation (EU) No. 10/2011
Basic provisions concerning materials with which foods make contact are set forth in Regulation (EU) No. 1935/2004 to eliminate discrepancies among the regulations of EU member counties. Regulation (EU) No. 10/2011 contains speciﬁc rules to ensure the safe use of plastic materials and other products that are intended to come into contact with foods.
Operating temperature range for belts
The operating temperature ranges for SUNLINE belts have been determined so as to take into account the strength of not only the belt itself, but also the joints. Due to the signiﬁcant deterioration in strength that room-temperature gluing and ﬁnger joints exhibit at high temperatures, use of these belts under conditions that would expose them to high temperatures over extended periods of time should be avoided. They can withstand temperatures in excess of the operating temperature range for short periods of time (about 5 min.), for example to allow cleaning of the belt.
In addition, please review the dry- and wet-heat operating temperature ranges as the degree of the eﬀect on the belt varies greatly depending on the amount of humidity present. If the belt surface temperature will range from -10 ํC to 0°C, choose a model with ﬁnger joints or hot lap joints. Models with cold lap joints should not be used under those conditions. If the belt surface temperature will range from -40°C to -10°C, choose a model with ﬁnger joints. Models with hot or cold lap joints should not be used under those conditions.
Cleaning and sterilization
Food manufacturing processes incorporate heat sterilization (using hot water or steam) that includes not only food products, but also mechanical equipment (conveyor belts) in order to ensure long shelf life and safety. Exposure of the polyurethane belts that are typically used with food products to wet heat will hasten joint damage as well as the degradation of the belt itself, eventually rendering the belt unusable. If your application includes cleaning and sterilization (with wet heat at temperatures from 80°C to 100°C), use one of the belts listed in the table to the right.
- The wet-heat operating temperature range is -10°C to 80°C for continuous operation and 100°C for momentary exposure (around 5 min.).
- If equipped with table supports and a cover for the bottom surface, use at a length of 10 m or less and a belt speed of 10 m/min. or less. The travel resistance increases when the belt is wet, which may lead to issues such as slippage when operation starts.
- SUNLINE belts not designed for use in wet-heat applications should be cleaned using cold or warm water at a temperature of 40°C or less. If using a cleaning agent, avoid use of powerful products such as those that are strongly alkaline.
- The SL-S8935N and SL-S8936N have a Fuororesin flm surface.
SUNLINE Belts can be joined using hot or cold jointing methods. Joint types include ﬁnger, overlap, lace (fastener), but most common are ﬁnger or overlap.
- Finger joints
Small pulleys and knife edges require ﬂexibility, so smooth belt surfaces and precision thickness is required. This type of joint is not appropriate for high temperature areas or for roller applications with clinging matter on the belt.
- Overlap joints
Overlap joints include hot joint and cold joint. Hot joint is more durable. Hot wrap is generally used where heat and humidity resistance is required. With one ply belts, ﬁnger joint is recommended because of better appearance and higher ﬂexibility compared to hot joint and cold joint, which may cause unevenness on belt surface.
- Double Finger joints (specialty)
Combination Finger and overlap joint. Easy use on small pulleys, and strong against foreign matter. Applicable for 2 ply belts.
- Lace joints
Simple joining method using metal clips or fasteners to easily join and replace belts. However, joint strength is inferior to hot and cold joints.
Skiver joints are also possible. Please contact Bando or your distributor.
V-guides can be used to prevent snaking. They can also be used to prevent products from falling oﬀ a conveyor by attaching them to the top of the belt, as V-guides are longitudinally Flexible.
- Effective in snaking and spillage prevention
- Heat vulcanization allows for use on small pulleys
- Nontoxic and odorless
