Does Corn Products only make products from corn?

Corn Products U.S., as well as our Canadian affiliate Casco and Mexican affiliate CPIngredientes, primarily use #2 dent corn. A variety of products made from tapioca may be sourced from our South American and Asian affiliates.

What is meant by the term dextrose monohydrate?

Dextrose crystallizes in either the monohydrate or anhydrous form. In the monohydrate form, a molecule of water is bound within the dextrose crystal. Anhydrous dextrose crystallizes with essentially no water. Therefore, dextrose monohydrate refers to the product that contains moisture, which is typically 8.5%.

What is the difference between corn syrup and glucose syrup?

Corn syrup and glucose syrup both describe liquid sweeteners made from the hydrolysis of starch. Corn syrup is a domestic term that indicates the product was indeed made from corn starch. However, in other parts of the world where wheat, tapioca, potato, rice, and corn starches are used, the generic term glucose syrup is used except when the starting material must be specified.

How do you determine whether a starch is made from regular corn or waxy corn?

All starches contain amylose and/or amylopectin. Regular corn starch contains 25% amylose and 75% amylopectin while waxy corn starch contains 100% amylopectin. When using a typical iodine staining technique, amylose stains blue while amylopectin stains reddish brown when viewed under a microscope. By using this method, waxy corn starch will appear reddish brown while regular corn starch will appear blue (blue color of amylose dominates reddish brown color of amylopectin).

Problem

Low viscosity at the storage tanks

Common Causes
  • Low viscosity adhesive coming from mixer
  • Finished batch temperature too high
  • Temperature of cooked portion too high
  • Bad temperature controller

  • Temperature viscosity control (TVC) system set too high
  • TVC controller out of calibration
  • Adhesive returning from machine at an elevated temperature
  • Finished batch temperature too high

  • Bad bearings on the supply/return pump
  • Storage tank agitators running continuously
  • Agitator timers not operating properly
  • TVC system controller malfunctioning
  • Poor heat transfer from TVC coils
  • TVC water too hot
  • TVC coils coated with gelled adhesive
  • TVC water too cold
  • TVC circulation pumps not operating
  • Unwanted water in adhesive
  • Wash water coming back from corrugator
  • TVC coil leaking inside storage tank
  • Over-shearing of the adhesive
  • High rpm supply and return pumps
  • Too many elbows in the supply and return lines
  • Supply and return line pipe diameter too small
  • Pipe size reductions in supply and return lines
  • Partially open valves in supply and return lines
  • Air pressure too high on air diaphragm pumps
  • Old adhesive (stored too long)
  • Adhesive treated with resin (WPA) mixed with domestic adhesive
  • Low solids adhesive formula
  • Microbiological contamination of adhesive

Problem

High viscosity at the storage tanks

Common Causes
  • High viscosity adhesive coming from the mixer
  • Adhesive viscosity "growing' in storage
  • Too much caustic in the formula
  • Scale out of calibration
  • Caustic meter out of calibration
  • Not enough borax in the formula
  • Borax timer set improperly
  • Wrong type of borax (5 mol vs. 10 mol)
  • Adhesive cold
  • TVC system not operating properly
  • Loss of steam pressure in the plant
  • Storage tank agitators not operating properly
  • Alkali-sensitive starch

Problem

Low viscosity at the machine

Common Causes
  • Excessive adhesive temperature in the starch pan
  • (between 110-1 20T)
  • Incorrect storage tank temperature
  • Incorrect TVC water temperature
  • Starch feed and return line exposed to steam lines
  • lnsulate these lines for better temperature control
  • Starch feed line running over top of single facer
  • Increase starch flow through the pan
  • Adhesive temperature increases the longer it remains in the pan
  • Higher temperatures lower the viscosity
  • Water dripping into the starch pan
  • Condensate from steam showers
  • Partially open valves in the starch feed and return lines
  • Flow restriction will create shear causing a drop in viscosity
  • Air pumps feeding or returning adhesive running at high PSI levels
  • Bad Viking pump (weak suction) creates too much shear
  • Pumps not sized properly for the corrugator
  • Plant has doser
  • Recirculating the adhesive causing a drop in viscosity
  • Low viscosity adhesive coming from the storage tanks

Problem

High viscosity at the machine

Common Causes
  • Low adhesive temperature
  • Cold weather outside causing the temperature drop
  • Very high temperature in the starch pan (in excess of 110° F)
  • Pressurized machine running high solids over 30%
  • Excess heat inside the chamber causing water loss
  • Chemicals in formula are out of ratio (borax to caustic)
  • Steam leak directly into the pan
  • Steam leak blowing into a starch line
  • Poor agitation or no agitation of the adhesive held in storage
  • High viscosity adhesive coming from the storage tanks

Problem

Viscosity decrease after overnight or weekend storage

Common Causes
  • Cleanup water returned to storage tanks
  • Agitators/circulating pumps left running
  • Circulating lines full of water
  • TVC system not working properly
  • Water leak from the TVC coil
  • Temperature of the adhesive too high
  • Insufficient amount of cooked starch in the formula to hold viscosity properly
  • Primary portion of the formula is overcooked
  • Bacteria

Logistics — Capabilities

What major issues are affecting transportation for Corn Products in 2008 and what actions will be taken to minimize the impact?

Logistics is still evolving to the continuous change in operation and regulations since the tragedy of September 11th. The threat of Bio-terrorism, governmental policy and self-regulation impacts cost and service. We have addressed this at CPI by working with a finite number of key carriers. This allows CPI to work closer with each carrier to minimize the impact of the changes, monitor performance and insure continuous improvement.

The second greatest challenge this year will be to minimize the impact of the U.S. driver shortage. Internally, we are working to improve loading efficiencies and have already set up an appointment schedule to relieve congestions. Externally, we hope to work with our carriers and customers where possible to: 1) shift delivery requirements to off-peak hours of operation; 2) provide schedule flexibility; 3) improve inventory management and, where appropriate, reduce washes for certain bulk trailers.

What do I do if my shipment arrives damaged?

Immediately contact your Customer Service Representative. Depending on the mode of delivery, specific steps will need to be taken to insure that the loss is properly documented and processed. Once we are notified of the problem, we will contact the involved carrier, document the loss and if required schedule an inspection.

What is the maximum shipping weight by truck, rail?

Truck shipments are subject to Federal and State regulations on the maximum gross weight of the vehicle and the maximum weight per axle (Bridge Formula). Generally we are able to load:

  • Bag products — up to 43,000 pounds
  • Dry bulk products — 48,000 to 50,000 pounds
  • Liquid bulk products — 50,000 to 53,000
    • Specialty light weight trailers and chassis allow maximum haulage where appropriate.
  • Rail shipments are subject to the maximum gross track capacity over the route of movement and the car capacity. In general rail track is graded to either 263,000 or 286,000 pounds.
  • Bag products/box cars — up to 132,000 pounds
  • Dry bulk products — up to 210,000 pounds depending on the car capacity and track allowance.
  • Liquid bulk products — up to 220,000 pounds depending on the car capacity and track allowance.
How much free time is allowed for unloading a bulk shipment?

Currently our carriers are contracted to allow up to two hours free time (with some exceptions, at one hour) for unloading and charges for detention will vary depending on the carrier and region but range from $40 to $50 per hour. However based on the new hours of service, loading and unloading delays have a greater impact on driver utilization. In this light, we see free time reducing to one hour and the charge increasing to $75/hour.

How much lead time should I provide when placing an order?

Lead time is dependent on the origin of the product, destination and method of transportation. But, typically placing an order with a 24hr. – 48hr. lead time is sufficient.
