Spiral Chutes | Gravity Chutes

Over the past 15 years, Astro Metal Craft has become the go-to manufacturer for metal spiral gravity chutes. This is especially true for many major food processing companies. Our clients trust our expertise in stainless steel metal fabrication. The ability to design for efficient manufacturing, and subsequently build the food processing equipment puts as a desirable partner for engineering firms that design material handling systems, contractors, and plant managers.

Spiral Chute Conveyor

When it comes to lowering food or other products efficiently from one level to the next without breakage, our spiral chute conveyer system is the perfect solution. This is because take up very little floor space, and require minimal maintenance. They are also clean and sanitary.

Gravity Chute

The spiral let-down chute gravity chutes are all designed for each specific application because there is a great variation in the “slide” of the product. This includes the vertical drop, desired speed of movement, volume moving, and equipment already in place. Of course, some operations use different features. Examples of these are slide gates, exit chutes and tank/holding areas to maximize efficiency. In addition, we are able to custom build or fit retroactively.

Professional Quality and Experience

Nevertheless, we put a food grade finish on chutes as required. However, other applications employ chutes out of carbon or stainless steel with a rougher finish.  Therefore, saving on the cost of finishing. Plus, our skilled welders have years of experience. Indeed, every project completed is from quality workmanship.

We draft your project in SolidWorks. SolidWorks is a popular 3D drafting program. After drafting, we send the prints to you for approval.  In most cases, we recommend starting with a smaller test chute. Adfter that, adjustments may be needed in the pitch. This is due to the various amount of “slide” in various products.

Considerations in Design

  • Specifications based on materials
  • The density, usually in pounds per cubic foot
  • Size and geometry of the material
  • Pounds and volume per hour
  • The distance of the drop
  • How the chute will load from the top (coffee beans vs. frozen hamburger patties)
  • Tank or other features incorporated
