Food Safety in Food Manufacturing

Inherent Hygienic Design

The fundamental reason for applying hygienic design principles is to prevent contamination of food products. Equipment and factories of poor hygienic design are difficult to clean. Equipment and factories which are difficult to clean will require more severe procedures, using more aggressive chemicals as well as longer cleaning and decontamination cycles. Consequences are higher costs, reduced availability for production, reduced lifetime of the equipment and more effluent.

Powder Feeding/Discharging

Food manufacturing is a highly challenging business because of the involvement of high standards of hygiene operation and food safety, it's even stringent with the dry food sector, because of the characteristics of the particulate materials that are not only complicated and unpredictable but also susceptible by the environmental conditions.

Two long lasting issues that are troubling the powder food manufacturers and dragging down the overall performance of the industry, one is the powder bridging, and the other is the execution of equipment cleaning and disinfection, which are still lack of effective solutions to this day. RIGHTER challenges the status quo and innovated the powder conveying equipment that not only solved the problems but also possessed with the following features.

Full accessibility
Thorough cleanability
Optimized flowability
Capability of CIP and SIP
Easy to use and user friendly

Factory Safety

In powder food processing, hygienic risk is not alone, the other colossal concern is the risk of dust explosion. It is presumed that all kinds of powders are prone to explode when the surrounding environment condition meets the ignition threshold.

RIGHTER equipment are designed to maintain no vibration, no heat generating, no dust floating while in operation, and always keeps powder tightness internally and externally, as to fulfills the ATEX/IECEX requirements and can be used in zone 21/22.

Bonding

For the purpose of controlling static electric hazards, the process of connecting two or more conductive objects together by means of a conductor so that they are at the same electrical potential, but not necessarily at the same potential as the earth.
[NFPA 77-2024 3.3]

New Mechanism

Accessibility, new method

Cleaning type as well as cleaning frequency for food production equipment varies with the different type of material. In some extremely demanding cases, it’s mandatory to clean and disinfect the equipment in a matter of few hours in order to eliminates the microbes. Nevertheless, the shortcomings with thorough cleaning and easy access are still exhibiting when operating equipment of the prior art.

Targeting to reduce the hassle, RIGHTER engineers adopted the asymmetric structure integrated with “Bearing-Free” mechanism that allows the operator to remove the rotor from the rotary valve within 3 minutes using just a simple hand tool, and vice versa. Then, dry- cleaning and inspection is available at any given time.

This one of a kind, state-of-the-art technical breakthrough reduces the stress and strain on the operator. Thus improves the performance and reliability of operation and the reduction in the probability of wrong doings.

Blow-Down

Adhesive, cohesive material stick on the surfaces wherever and whatever they pass by, the material gradually build up and then narrowing the spaces and eventually bring down the production efficiency. There is no effective solutions to prevent the build-up but only capable of controlling it down to a slower rate. Study and testing show that “Blow-Down” is an effective and better solution to deal with sticky materials. The method is about using the shear force of compressed air to blow into the deep of rotor pockets, to blow-down the materials. The rotary valve can connect to either bag/box/drum or pipeline under “Blow-Down”.

The Rotor

The shaft-less rotor allows the operators to use only a hand tool to assemble/disassemble the rotor with ease. The rotor is always maintaining at the axial center datum when rotating. This innovation eliminates the need of osculation detection sensors.

The Powder Feeder-Discharger

RIGHTER Powder Feeder-Discharger is an integration and collaboration of a Powder Bridging Breaker, a Rotary Valve and an Entrainment module. The unity is not only thoroughly powder tight and cleanable but also capable to do CIP/SIP integratively with the system, on top of that it’s easy to use and user friendly. Here are its outstanding features :

Air-Lock
Powder tight
Blow-down
All-over Electro-polishing
Ergonomic consideration

Powder Bridging Breaker

The role of funnel is distinct from the silo in the storage tank. The function of a silo is to store and retain materials, while the funnel at the bottom, focus more on effective discharging. The cross-section area of the funnel gradually decreases in the direction of flow, forming an inverse cone. The powder flow in the funnel is restricted and becomes increasingly compact to higher density; jamming is bound to happen despite the particle's characteristics.

The cause of powder bridging is complicated. The impact severity varies due to a number of particle and environmental factors, making it difficult to choose and adopt one single measure to counteract all types of powder bridging. It is easy to tell if a silo has a powder bridging problem by looking for ‘hammer rash’ on the silo wall. If the powder is not moving freely, the operators will mostly hit the silo.

Generally, the measures to solve powder bridging are knocking, vibration, or air blowing, but the results from these methods are not entirely satisfactory, and they simultaneously cause other problems e.g. damaging the storage tank, making the powders even more compact, etc., that require additional measures.

In the case that material stops flowing, it directly affects the product quality and operation efficiency. Solving the powder bridging is the most urgent task for the factories. When all measures seem to have failed, the Powder Bridging Breaker is your righter choice.

The Powder Bridging Breaker

The powder bridging breaker uses the power source from a gear motor to drive a wiper to rotate inside the funnel. In operation, the slow and steady motion of the wiper provides the momentum that breaks any forms of powder bridging

Features

Hygienic design
Powder tightness, internal and external
Easy installation
CIP/SIP capable
Minimal powder retention
No vibration, No noise,
No heat generating
No dust floating in the hopper
Tri-Clamp connection available

How it works

The Powder Bridging Breaker is made of investment casting stainless steel, it is robust and corrosion-resistant and can be applied to various types of materials.

The housing is a ring structure with a large opening to allow the powder to pass through without obstruction. A gear motor is mounted on the housing to provide the torque. The torque is transferred to the upper cap via a series of transmission mechanism, the upper cap rotates and drives the wiper to rotate in low speed.

Powder tightness is assured by effective multiple sealing measures. Cleaning is simple and easy without the need to use any tools.

Powder Tight

Sealing construction compliant to hygienic standard
Dynamic sealing prevents powder ingress and egress
Degree of protection : IP 58 internal and external
Dynamic sealing : PTFE seal with back-up ring, Labyrinth sealing, Oil seal and Air-Purging

Cleaning and maintenance

Simply twist and turn the upper cap and wiper to disassemble, and vice versa, cleaning and inspection can be done at any given time
Wiper maintains approximately one inch distance from the funnel wall
Replacement schedule of sealing materials is under the discretion of the user

** Powder Bridging Breaker is patent pending wordwide.**
