Multi Scale Distribution System

The Storveyor™ Product Storage System

The Smalley Storveyor is the answer to uniform flow of product to packaging. The Storveyor can provide surge protection for packaging by providing in-line storage of product between processing and packaging. Storveyor systems will also provide off-line storage of product when the packaging machine is down, or when production exceeds the limits of packaging or when there is a time frame difference between processing and packaging.

Smalley offers a wide range of options to meet most operating requirements. Last-in-first-out (LIFO) systems offer a very economical method of packaging surge protection and temporary storage of product during short packaging stoppages. Storveyor optional intake units offer First-in-first-out (FIFO) capability when storage time is a factor. FIFO systems feature storage loading units of several designs which have been developed for gentle handling of most food products. Storveyor designs are selected to meet the exact requirements of each application, no matter how small or how complex the system requirements, Smalley Storveyor is the answer to in process product storage.

Tote Fill gentle Spiral Letdown Tote Fill Systems

Smalley Manufacturing offers a tote fill unit – “GSLS” – specifically designed to fill totes efficiently while lowering the product gently into the bin. The system incorporates a steel holding bin mounted on a sturdy tubular construction platform. The product is then gently and precisely conveyed from the bin via an electromagnetic feeder on to the constant velocity spiral.

The spiral is specifically designed to maintain a constant conveying speed that will reduce degradation to the product. Once the tote is in position and presented for filling by the roller feed system, the spiral will lower to within a foot of the bottom of the tote, then slowly raise as the product fills the tote, leaving a minimum amount of product free-fall that will in turn reduce the degradation.

The product and tote weight is constantly monitored by load cells sitting directly below the tote. A leveling shaker is also included to condense the volume of the product into the tote. Once the tote reaches the desired weight, the spiral will fully retract and the now filled tote will be conveyed into a staging area while a new tote enters the system.

The control system is state of the art using Allen Bradley components with a fully integrated tough screen for easy operation. Our controls shop is UL listed and strictly complies the latest codes; we will also engineer our controls using components of your preference.

Dependent upon the sanitation requirements, the unit can be manufactured from all stainless steel for complete wash-down, or more economical carbon steel with stainless contact parts.


  • Compact and robust design
  • Gentle on your products
  • Fully automated system
  • Tote staging can be increased or decreased
