Described herein are systems and methods for the automated adjustment of flour property measurement equipment such as dough rheometers. The systems and methods allow measurements of flour and dough to be performed on different rheometers with consistent results, regardless of the manufacturer or location of the rheometers. The systems and methods described herein allow a second rheometer, for example, that is deployed in the field to provide results that are consistent with a first dough rheometer, for example, that may be at a different location, or the same location but of the same or different manufacturer. The systems and methods can be used to calibrate, remotely and in real-time, dough rheometers that are deployed in various locations.

A system for measuring effects of vibration on rheometric properties of a fluid sample. The system includes a receptacle configured to hold the fluid sample and receive a probe extending from a rheometric measuring device. A vibration generator is configured to vibrate the fluid sample within the receptacle while the rheometric measuring device measures the rheometric properties of the fluid sample. A vibration control module is configured to control frequency at which the vibration generator vibrates.

There is provided a system and method for the measurements of viscoelastic properties of a soft sample in which the system incorporates a sample holder that has a membrane with a flexural rigidity that is less than the flexural rigidity of the main body and allowing vibration of the membrane-sample vibration unit in response to a vibration excitation to create resonance vibration modes that are detected to derive the viscoelastic properties.

An universal machine is comprised of the arrangement of a set of modules (CM) that make up means of rheological and mechanical tests for the assessment of longitudinal forces perpendicular to the rotation direction of an alternate current servomotor. Its modules are comprised of: a) structural organization; b) electronic components cabinet of the electronics system (St)/(Sw); c) dry gear reducer; d) alternate current servomotor; e) fast coupling system for changing geometries; f) test containers, as well as devices for the execution of materials in hardened state; g) load cell device for recording regular longitudinal forces. The machine provides the interconnection with a data processing system (PC) and the aforementioned modules (CM) are controlled by a specific electronic system (St) for speed control, torque control and rotation direction.

A method is provided for monitoring a flow behavior of mixed components without requiring additional instrumentation or sampling. The method is carried out by determining ratios of the power required to rotate a mixing impeller at different rotational speeds and then comparing the ratios. Characteristics about the mixed components are determined based on differences between the ratios.

Disclosed is a system and method for determination of the viscoelastic properties of a viscoelastic substance based on the type of non-mechanical forces which drive the viscoelastic substance inside a channel. These forces may comprise capillary, gravitational, electric, magnetic, or any other type where neither a pump nor any relative velocity between solid surfaces is needed to induce the transport of fluid medium. As a result, the design of the system remains simple, and the system is capable of yielding results devoid of noise produced by mechanical forcing. The present disclosure a general analysis describing extraction of viscoelastic properties by observing flow-systems driven by any non-mechanical means, including capillary force and electro-osmotic force. Such time-dependent penetration depth may be recorded by optical, electrical or mechanical means and may further include the use of a computing device.

An apparatus and method are disclosed for accurately determining viscosity of Newtonian and non-Newtonian fluids in the field or in-service by using a potable field viscometer. The portable field viscometer includes a vertical disposable (or reusable) sample insert tube filled with the liquid which the viscosity is to be determined. Using fins on the needle surface, a needle having a known density is made to fall through the liquid in the disposable (or reusable) sample insert tube coaxially. Using the time that the needle takes to fall between two known distance marks on the extension bar attached the top of the needle or transducers such as light, laser or magnetic, the velocity of the needle falling through the liquid is determined. Thus, the viscosity can be calculated by using the velocity of a needle. In the method, viscosity, shear rate and shear stress can be determined according to the disclosed method.

Methods are provided for predicting the properties of an asphalt emulsion, such as an asphalt emulsion that contains an asphalt fraction derived from a plurality of crude oils. Corresponding tools are provided to allow for visualization of the predicted asphalt emulsion properties. The properties of the asphalt components in an asphalt fraction for forming an emulsion can be represented based on using a simplified functional form to represent each emulsion property of each asphalt component. The emulsion properties of an asphalt fraction, composed of a plurality of asphalt components, can be modeled based on a linear combination of the emulsion properties of the asphalt components.

Process for evaluating the mechanical performance of a filler gel, comprising the step consisting in subjecting a sample of this gel to oscillating mechanical stresses making it possible to determine the elastic modulus G and to deliver a score representative of the integration of G over the stress and/or the deformation strain within a stress and/or strain interval that includes values of the modulus G encountered beyond the linear viscoelasticity plateau.

The present disclosure provides improved viscosity measuring assemblies, and related methods of use. More particularly, the present disclosure provides advantageous measuring assemblies configured to measure the viscosity of samples/fluids (e.g., opaque or transparent liquids) using microchannels. The present disclosure provides for a viscosity measuring assembly (e.g., hand-held electronic measuring assembly) that is configured to measure the viscosity of samples/fluids (e.g., opaque or transparent Newtonian and non-Newtonian liquids, including blood, etc.), in a short period of time (e.g., within a couple of minutes) utilizing only about a droplet of fluid. The viscosity measuring assembly can include a substrate having a microchannel, a light source (e.g., a collimated low coherence light source), and a sensor (e.g., photodiode). The micro-channeled substrate may be disposable, and some of the other components may be reusable since they are substantially not directly exposed to the sample during operation of the viscosity measuring assembly.
