Description
本発明は、食材水処理場からの汚損水を流入する排水ピット装置にて、混入汚染物などが付着汚染することを自洗により確実に防止して汚染拡大を未然に防ぐことを可能にして、食製材の衛生上及び安全上の全てに安心なＨＡＣＣＰ用の排水ピット装置に関する。 The present invention makes it possible to reliably prevent the spread of contamination by self-cleaning in a drainage pit device into which contaminated water from a food water treatment plant flows, from adhesion and contamination of mixed contaminants. , relates to a drainage pit device for HACCP that is safe in terms of hygiene and safety of food materials.
食材工場、給食センター、学校給食、病院、レストランの厨房等における床排水ピット装置は、主に食材衛生法によるＨＡＣＣＰにより衛生面が強化される。
ＨＡＣＣＰ（Ｈａｚａｒｄ（危害），Ａｎａｌｙｓｉｓ（分析），Ｃｒｉｔｉｃａｌ（重要），Ｃｏｎｔｒｏｌ（管理），Ｐｏｉｎｔ（点））システムは、食材製造工程を細分化し、工程ごとのリスク管理を行い、問題がある場合は、どの工程に原因があるのかを迅速に究明し対応するものである。
而して、従来の排水ピット装置は、コンクリート製のダスター溝を利用していたため経年劣化によりクラックが発生し徐々に拡張されて、そこに排水が侵入して汚水漏れを惹起する。これらを放置するとクラック部に汚染物が増殖・濃縮する恐れがある。Floor drainage pit devices in food factories, school lunch centers, school cafeterias, hospitals, restaurant kitchens, etc. are mainly hygienic based on HACCP under the Food Sanitation Act.
The HACCP (Hazard, Analysis, Critical, Control, Point) system subdivides the food manufacturing process, performs risk management for each process, and takes action if there is a problem. , to quickly determine which process is causing the problem and take appropriate action.
Since the conventional drainage pit device uses a concrete duster groove, cracks occur due to deterioration over time, and the groove gradually expands, allowing drainage water to enter the groove and causing sewage leakage. If these are left unattended, there is a risk that contaminants will grow and concentrate in the cracks.
このため近年は、抗菌性、抗カビ性、耐摩耗性、耐熱性、耐薬材性に優れているステンレス（ＳＵＳ）製或いは樹脂製の受枠成形、ダスター溝成形の一体型のダスターピット及びネオトラフ等のダスター溝等による床排水ピット装置が開発された。
具体的な構造デザインとしては、食材の残菜・汚物・塵埃が付着し難く、清掃し易いように丸構造や楕円構造を採用し、大容量の箱型の隅部には曲面を成形し、底部には水勾配を形成する等の対策をして溜りが少なく円滑な汚損水の排水を可能にしようとしている。
叉、従来の前記ステンレス製の排水路にして汚損水路表面の凹凸を改善しているが、逆説的に汚損水排水路の表面への多少の汚染物の付着は免れず、累積による定期的に大がかりな掃除をする必要がある。For this reason, in recent years, stainless steel (SUS) or resin receiving frames, integrated duster pits and neo-troughs with duster groove molding, etc., which have excellent antibacterial, anti-mold, abrasion resistance, heat resistance, and chemical resistance, are being used. A floor drainage pit device using duster grooves, etc., was developed.
As for the specific structural design, we have adopted a round or oval structure to prevent food scraps, dirt, and dust from adhering to it and to make it easy to clean.The corners of the large-capacity box shape have curved surfaces. Measures such as forming a water gradient at the bottom are being taken to ensure smooth drainage of contaminated water with less accumulation.
In addition, although the unevenness of the surface of the contaminated water channel has been improved by using the conventional stainless steel drainage channel, paradoxically, some contaminants still adhere to the surface of the contaminated water channel, and due to accumulation, the irregularities on the surface of the contaminated water channel are improved. I need to do some major cleaning.
本発明は、食材水処理場からの汚損水を流入する排水ピット装置にて、該汚損水を連続流水しながら流水路内で流水接触面への汚染物の付着及び累積を防止して、食製材の衛生上及び安全上の全てに安心なＨＡＣＣＰ用の排水ピット装置を提供する。 The present invention uses a drainage pit device into which contaminated water from a food water treatment plant flows, and prevents contaminants from adhering to and accumulating on surfaces that come in contact with the flowing water in a water channel while continuously flowing the contaminated water. We provide a drainage pit device for HACCP that is safe in all aspects of lumber hygiene and safety.

The drainage pit device of the present invention into which contaminated water flows from the food water treatment plant is a drainage pit device that facilitates the maintenance and management of food hygiene and is safe in terms of hygiene and safety. That is, by applying the above-mentioned water-based inorganic paint to the contaminated water contact surface of the drainage pit equipment, in the food processing line (e.g. food pre-processing process → processing process → food product shipping process), from the food pre-processing process to the food material shipping process. By applying a water-based inorganic paint as described above to the contact surface of the contaminated water of the drainage pit device that treats the contaminated water that flows out, the adhesion of food scraps, filth, dust, germs, bacteria, viruses, etc. can be prevented. The above-mentioned water-based inorganic paint washes the food by itself to prevent proliferation and accumulation, thereby establishing HACCP that is safe in terms of food hygiene and safety.
