Pasta plant extraordinaire

The only way for this new pasta producer to meet the needs of three different market segments is to have a packaging operation designed for maximum flexibility.

Packaging in multiple sizes for multiple markets simultaneously-that was the key objective as Dakota Growers Pasta Co. a startup wheat growers' cooperative designed its 300-sq-ft plant in Carrington ND. The plant went into production in November 1993.

The major markets served by the firm are

*foodservice and institutional users

*retail stores (primarily for private label customers but DGP also packs under its own brand) and

*processors that use pasta as an ingredient in the packaged foods they market.

Most of the firm's business is in the first two categories as DGP packs 240 SKUs for its foodservice and institutional customers and 277 SKUs on the retail side. That kind of variety and the need to be competitive in three very different markets meant that DGP had to be as flexible as possible in its approach to packaging.

"Some of the big pasta firms have high volumes in one particular product so they can dedicate a high-output pasta production line to one packaging line" says plant superintendent David Tressler. "But that kind of dedication was never an option for us because we have too many customers with too many packages. We had to be able to go to many different packaging destinations simultaneously yet we wanted to be able to produce the pasta in large batches. This keeps us keep from having to start and stop and it minimizes waste.

"With our system I can total up all the orders for say spaghetti in a given diameter and produce a batch that will fill all those orders regardless of what market segment it's for or what style of package it requires. I don't have to think at the processing stage that I have to hit such and such a packaging line so the amount I produce isn't governed by how much that one packaging line can handle."

DGP can operate this way because of two product conveying systems that serve as the link between processing and packaging. One handles long goods like spaghetti and linguini while the other is for short goods like macaroni and shells. In fact the area devoted to packaging is split just about down the middle long goods on one side and short on the other.

The two sides combined are capable of packaging about 2 lb of pasta per week. Packaging is done 16 hr per day processing 24 an arrangement that allows about 8 hrs of in-process product accumulation.

Five machines for long goods

On the long goods side product is directed to any one of five packaging machines by means of the Pasta Elecon® Multi-Axis Conveying System from Gough Econ Inc. (Charlotte NC). It uses buckets to carry product to the packaging lines. What makes it unusual is it substitutes a single-chain drive instead of a two-chain approach. Dual-chain drive is fine for linear transport but it can't negotiate a turn because the chains are of fixed lengths. Traditionally to send long goods left or right required a transfer point of some kind and transferring products as fragile as spaghetti invites problems.
